How to Fix FATAL error Failed to parse input Document ?

When encountering the "FATAL error Failed to parse input document" error, it typically indicates that there is an issue with the code used to parse the document. To fix this error, you can follow these steps:

Review the parsing code: 

Check the code responsible for parsing the input document. Ensure that it is correctly implemented and follows the correct syntax for the chosen parsing library or approach.

Validate the input document: 

Before parsing the document, validate its format and structure. Use a document validator or a specific validator for the document type you are parsing to ensure it adheres to the expected standards. This can help identify any syntax errors or inconsistencies in the document.

Confirm the input document's compatibility: 

Ensure that the parsing library or approach you are using supports the document type you are trying to parse. Some libraries specialize in specific document formats, so double-check that the chosen library is suitable for your document.

Check the input document's encoding: 

Verify that the encoding of the input document is correctly specified and matches the one expected by the parsing code. Inconsistent or incorrect encoding can cause parsing failures.

Handle exceptions: 

Wrap the parsing code in appropriate exception handling to catch any errors or exceptions that may occur during the parsing process. This allows you to handle and report errors more gracefully, providing more information about the specific issue.

Debug the code: 

Use debugging techniques to narrow down the problem area in your parsing code. Print or log relevant variables, check intermediate results, and step through the code to identify where the parsing error occurs. This can help pinpoint the specific issue and allow for more targeted troubleshooting.

Consult documentation and resources: 

Consult the documentation and resources related to the parsing library or approach you are using. Look for specific examples, code snippets, or troubleshooting guides that can provide insights into common parsing issues and their solutions.

Seek community or expert help: 

If you are still unable to resolve the issue, consider seeking help from the community or experts familiar with the specific parsing library or document format you are working with. Forums, developer communities, or support channels for the parsing library or document type may offer valuable assistance.
