Failed to parse mapping resource: 'file

It seems like the file you are trying to parse as a mapping resource is not valid or cannot be found.

Here are some possible reasons and solutions:

- The file path is incorrect: Check the file path and make sure it is pointing to the correct location. Double-check for any typos or mistakes in the file name or directory structure.

- The file is not a valid mapping resource: Make sure the file you are trying to parse is in a valid format for a mapping resource. This could be a YAML or XML file, for example. Check the documentation of the library or framework you are using to see what format is expected.

- The file is corrupted or incomplete: Try opening the file and checking if it is complete and not corrupted. If you suspect the file is corrupt, try creating a new one or restoring it from a backup.

- The file permissions are incorrect: Make sure you have the necessary permissions to access and read the file. If you are running your application in a restricted environment, such as a Docker container, you may need to set the appropriate file permissions.

Once you have identified the issue, try fixing it and parsing the mapping resource again. If you are still having issues, consult the documentation or seek help from the community or support team for the library or framework you are using.
