The error messages generated by the DITA Open Toolkit contain a message ID, severity information, and message text. This topic lists each error message generated by the toolkit and provides additional information that might be helpful in understanding and resolving the error condition.
Each message ID is composed of a message prefix, a message number, and a letter that indicates the severity (I, W, E, or F). The toolkit uses the following severity scale:
Informational (I)
: The toolkit encountered a condition of which you should be aware. For example, draft comments are enabled and will be rendered in the output.
Warning (W)
: The toolkit encountered a problem that should be corrected. Processing will continue, but the output might not be as expected.
Error (E)
: The toolkit encountered a more severe problem, and the output is affected. For example, some content is missing or invalid, or the content is not rendered in the output
Fatal (F)
: The toolkit encountered a severe condition, processing stopped, and no output is generated.

DOTA001F
Fatal
"%1" is not a recognized transformation type. Supported transformation types are common-html, docbook, eclipsecontent, eclipsehelp, html5, htmlhelp, javahelp, odt, org.dita-ot.html, pdf, pdf2, tocjs, troff, wordrtf, xhtml.
Default transformation types that ship with the toolkit include xhtml, eclipsehelp, pdf (or pdf2), tocjs, htmlhelp, javahelp, odt, eclipsecontent, troff, docbook, and wordrtf. Additional transformation types may be available if toolkit plug-ins are installed.
DOTA002F
Fatal
Input file is not specified, or is specified using the wrong parameter.
The input parameter was not specified, so there is no DITA or DITAMAP file to transform. Ensure the parameter is set properly; see DITA-OT common parameters (args.input) if you are unsure how to specify the input file.
DOTA003F
Fatal
Cannot find the user specified XSLT stylesheet '%1'.
An alternate stylesheet was specified to run in place of the default XSLT output process, but that stylesheet could not be loaded. Please correct the parameter to specify a valid stylesheet.
DOTA004F
Fatal
Invalid DITA topic extension '%1'. Supported values are '.dita' and '.xml'.
This optional parameter is used to set an extension for DITA topic documents in the temporary processing directory. Only "dita", ".dita", "xml", or ".xml" are allowed.
DOTA006W
Warning
Absolute paths on the local file system are not supported for the CSSPATH parameter. Please use a relative path or full URI instead.
If the CSSPATH uses an absolute path, it should be one that can still be accessed after the files are moved to another system (such as http://www.example.org/). Absolute paths on the local file system will be broken if the content is moved to a new system.
DOTA007E
Error
Cannot find the running-footer file "%1". Please double check the value to ensure it is specified correctly.
The running footer file, which contains content to be added to the bottom of each XHTML output topic, cannot be located or read. This is usually caused by a typo in the parameter value. You should also ensure that the value is not specified with "file:" as a prefix.
DOTA008E
Error
Cannot find the running-header file "%1". Please double check the value to ensure it is specified correctly.
The running header file, which contains content to be added to the top of each XHTML output topic, cannot be located or read. This is usually caused by a typo in the parameter value. You should also ensure that the value is not specified with "file:" as a prefix.
DOTA009E
Error
Cannot find the specified heading file "%1". Please double check the value to ensure it is specified correctly.
The running heading file, which contains content to be added to the section of each HTML output topic, cannot be located or read. This is usually caused by a typo in the parameter value. You should also ensure that the value is not specified with "file:" as a prefix.
DOTA011W
Warning
Argument "%1" is deprecated. This argument is no longer supported in the toolkit.
DOTA012W
Warning
Argument "%1" is deprecated. Please use the argument "%2" instead.
DOTA013F
Fatal
Cannot find the specified DITAVAL '%1'.
DOTA066F
Fatal
Cannot find the user specified XSLT stylesheet '%1'.
An alternate stylesheet was specified to run in place of the default XSL-FO output process, but that stylesheet could not be loaded. Please correct the parameter to specify a valid stylesheet.
DOTA067W
Warning
Ignoring index-see '%1' inside parent index entry '%2' because the parent indexterm contains indexterm children. According to the DITA Specification, the index-see element should be ignored if the parent indexterm contains other indexterm children.
This condition is ignored, as instructed in the OASIS DITA Standard.
DOTA068W
Warning
Ignoring index-see-also '%1' inside parent index entry '%2' because the parent indexterm contains indexterm children. According to the DITA Specification, the index-see-also element should be ignored if the parent indexterm contains other indexterm children.
This condition is ignored, as instructed in the OASIS DITA Standard.
DOTA069F
Fatal
Input file '%1' cannot be located or read. Ensure that file was specified properly and that you have permission to access it.
Please ensure that the input file path and file name were entered correctly.
DOTA069W
Warning
Target "%1" is deprecated. Remove references to this target from your custom XSLT or plug-ins.
DOTJ005F
Fatal
Failed to create new instance for '%1'. Please ensure that '%1' exists and that you have permission to access it.
DOTJ007E
Error
Duplicate condition in filter file for rule '%1'. The first encountered condition will be used.
DOTJ009E
Error
Cannot overwrite file '%1' with file '%2'. The modified result may not be consumed by the following steps in the transform pipeline. Check to see whether the file is locked by some other application during the transformation process.
The transform was unable to create files properly during the transform; results may not be as expected.
DOTJ012F
Fatal
Failed to parse the input file '%1'.
This message may indicate an invalid input file (such as accidentally specifying a PDF file as input rather than a DITA map file), an input file that uses elements which are not allowed, are not part or a DITA file that has errors and cannot be parsed as XML. You could also be using a specialized DITA document type that needs external plug-ins in order to be parsed correctly. The message issued by the XML parser should provide additional information to help diagnose the cause.
DOTJ013E
Error
Failed to parse the referenced file '%1'.
This message may indicate a reference to an invalid file (such as accidentally referencing a PDF or unknown XML file as if it was DITA), a referenced file that uses elements which are not allowed, or a referenced DITA file that has errors and cannot be parsed as XML. You could also be using a specialized DITA document type that needs external plug-ins in order to be parsed correctly. The message issued by the XML parser should provide additional information to help diagnose the cause.
DOTJ014W
Warning
Found an indexterm element with no content. Setting the term to ***.
An empty element was found, and will appear in the index as ***. This index term should be removed from the source.
DOTJ018I
Informational
Log file '%1' was generated successfully in directory '%2'. Any messages from the transformation process are available in the log file; additional details about each message are available in the DITA-OT user guide.
DOTJ020W
Warning
At least one plug-in in '%1' is required by plug-in '%2'. Plug-in '%2' cannot be loaded. Check and see whether all prerequisite plug-ins are installed in toolkit.
This will appear when one installed plug-in requires another in order to function correctly, but the required plug-in is not found. The installed plug-in will be ignored.
DOTJ021W
Warning
File '%1' will not generate output since it is invalid or all of its content has been filtered out by the ditaval file. Please check the file '%1' and the ditaval file to see if this is the intended result.
This may appear if filter conditions on the root element of a topic cause the entire topic to be filtered out. To remove this message, you could place any filter conditions on the reference to this file, which will prevent the build from accessing this file.
DOTJ022F
Fatal
Failed to parse the input file '%1' because all of its content has been filtered out. This will happen if the input file has filter conditions on the root element, and a ditaval excludes all content based on those conditions.
Either the input file or the ditaval file should change, otherwise your build is explicitly excluding all content.
DOTJ023E
Error
Failed to get the specified image file '%1', so it will not be included with your output.
Check whether the image exists in the source location or already exists in the output directory.
DOTJ025E
Error
The input to the "topic merge" transform process could not be found. Correct any earlier transform errors and try the build again, or see the DITA-OT User Guide for additional causes.
This message should only appear in the following cases: - Errors earlier in the transform prevented this step of the transform from running; correct any errors and try the build again.
An Ant build or plug-in is directly calling the toolkit's topic merge module, and is doing so improperly; in this case the Ant build or plug-in needs to be fixed.
In the past, problems have been encountered when calling this module with an absolute path; this should no longer be an issue, but may be fixed in older releases by updating the Ant build or plug-in.

|DOTJ026E|Error|The "topic merge" did not generate any output. Correct any earlier transform errors and try the build again, or see the DITA-OT User Guide for additional causes.|This message should only appear if an Ant build or plug-in is directly calling the toolkit's topic merge module, or if earlier errors resulted in problems with some of the content. If the topic merge module is called correctly, then this indicates a program error that should be reported to the DITA-OT development team, at DITA-OT bug and feature tracker.|
|DOTJ028E|Error|No format attribute was found on a reference to file '%1', which does not appear to be a DITA file. If this is not a DITA file, set the format attribute to an appropriate value, otherwise set the format attribute to "dita".|When referencing a non-DITA file, the format attribute should indicate the type of file referenced (such as "html" for HTML topics or "pdf" for PDF files). Otherwise, the transform may attempt to parse the referenced document as a DITA topic.|
|DOTJ029I|Informational|No 'domains' attribute was found for element '<%1>'. This generally indicates that your DTD or Schema was not developed properly according to the DITA specification.|The domains attribute is used in specialized DITA documents to help determine which domain elements are legal. This message will only appear if DITA specialization was not defined properly.|
|DOTJ030I|Informational|No 'class' attribute for was found for element '<%1>'. This generally indicates that your DTD or Schema was not developed properly according to the DITA specification.|All specialized DITA elements must define a class attribute to provide ancestry information. This message will only appear a specialized DITA element did not define a class attribute.|
|DOTJ031I|Informational|No specified rule for '%1' was found in the ditaval file. This value will use the default action, or a parent prop action if specified. To remove this message, you can specify a rule for '%1' in the ditaval file.|This informational message is intended to help you catch filter conditions that may have been specified improperly; if the value is correct, no action is needed.|
|DOTJ033E|Error|No valid content is found in topicref '%1' during chunk processing. Please specify an existing and valid topic for the topicref.| |
|DOTJ034F|Fatal|Failed to parse the input file '%1' (the content of the file is not valid). If the input file '%1' does not have a DOCTYPE declaration, please make sure that all class attributes are present in the file.|DITA processing is based on class attributes defined for every element. Usually these are defaulted in the DTD or Schema; if no DTD or Schema is used, the class attributes must be explicitly included in the map or topic.|
|DOTJ035F|Fatal|The file "%1" referenced by "%2" is outside the scope of the input dita/map directory. If you want to lower the severity level, please use the Ant parameter 'outer.control', and set the value to "warn" or "quiet". Otherwise, move the referenced file "%1" into the input dita/map directory.|This will appear when a topic is outside the scope of the map; for example, if the main input map references "../other-directory/some.dita". The result would cause an output file to be created outside of the output directory. See DITA-OT common parameters (outer.control and generate.copy.outer) for details.|
|DOTJ036W|Warning|The file "%1" referenced by "%2" is outside the scope of the input dita/map directory.|This will appear when a topic is outside the scope of the map; for example, if the main input map references "../other-directory/some.dita". The result would cause an output file to be created outside of the output directory. If you do not want to see the warning message, please use the Ant parameter 'outer.control', and set the value to "quiet". Otherwise, move the referenced file into the input dita/map directory. See DITA-OT common parameters (outer.control and generate.copy.outer) for details.|
|DOTJ037W|Warning|The XML schema and DTD validation function of the parser is turned off. Please make sure the input is normalized DITA with class attributes included, otherwise it will not be processed correctly.|DITA processing is based on class attributes defined for every element. Usually these are defaulted in the DTD or Schema; if validation against the DTD or Schema is turned off, the class attributes must be explicitly included in the map or topic.|
|DOTJ038E|Error|The tag "%1" is specialized from unrecognized metadata. Please make sure that tag "%1" is specialized from an existing metadata tag in the core DITA vocabulary.|This appears to indicate an error in creating specialized metadata elements. Please verify that the document type you are using is complete and complies with DITA Specialization rules.|
|DOTJ039E|Error|There is no target specified for conref push action "pushafter". Found in file="%1", element="%2". Please add before current element.|Please see the topic on Conref Push in the DITA specification for details on expected syntax for this function.|

|DOTJ042E|Error|Two elements both use conref push to replace the target "%1". Please delete one of the duplicate "replace" actions.|The conref push function was used to replace a single element with two or more alternatives. Only one element may directly replace another using conref push. See Conref Push in the DITA specification for more information about the conref push "replace" function.|
|DOTJ043W|Warning|The conref push function is trying to replace an element that does not exist (element "%1" in file "%2").|The target for a conref push action does not exist; please make sure that the syntax is correct and that the target exists. See the topic on URI-based addressing in the DITA specification for details on the expected syntax. If the syntax is correct, it is possible that the target was filtered out of your build using a DITAVAL file.|
|DOTJ044W|Warning|There is a redundant conref action "pushbefore". Found in file="%1", element="%2". Please make sure that "mark" and "pushbefore" occur in pairs.|Please see the topic on Conref Push in the DITA specification for details on expected syntax for this function.|
|DOTJ045I|Informational|The key "%1" is defined more than once in the same map file. The reference href="%2" is ignored.|No response is needed if the keys are defined as expected; this is informational only, to help catch incorrectly defined keys.|
|DOTJ046E|Error|Conkeyref="%1" can not be resolved because it does not contain a key or the key is not defined. The build will use the conref attribute for fallback, if one exists.|See the conkeyref definition for details on expected syntax and usage.|

Please correct the attribute so that it uses one of the allowed values.|
|DOTJ050W|Warning|Found an or reference to the term '%1', but that term is not defined in the index.|The Eclipse index will contain a value such as "See also otherEntry", but otherEntry does not exist in this index. The index reference will be broken unless this plug-in is always loaded into Eclipse with another plug-in that defines otherEntry as an index term.|
|DOTJ051E|Error|Unable to load target for coderef "%1".|The target for a coderef element, which specifies an external text-based file, could not be located or loaded. Please verify that the reference is correct.Note that for security reasons, references to code samples outside of the scope of the map directory are not supported by default, as this could allow a reference to access and display any restricted or hidden file on the system. If you are certain that the path is valid and the file should be loaded, the current workaround is to set a parameter to allow these references.

|DOTX030W|Warning|The type attribute on a %1 element was set to %3, but the reference is to a %4 %2. This may cause your links to sort incorrectly in the output.|The type attribute in DITA is intended to describe the type of the target; for example, a reference to a concept topic may use type="concept". Generally, this attribute is optional, and the DITA-OT build will automatically determine the value during processing. In this case, the specified type value does not match the target, which may cause your links to sort inappropriately.|
|DOTX031E|Error|The file %1 is not available to resolve link information.|The build attempted to access the specified file in order to retrive a title or short description, but the file could not be found. If the file exists, it is possible that a DITAVAL file was used to remove the file's contents from the build. Be aware that the path information above may not match the link in your topic.|
|DOTX032E|Error|Unable to retrieve link text from target: '%1'.
