The getSourceFiles function throws an error when file paths are unavailable in CWD

[bigdatasourav]

In file-based plugins like Terraform, we pass file paths from SPC files and use GetSourceFiles present in the plugin.QueryData to fetch the file; if we pass a fileName not current in CWD, the SDK returns an error - Error: failed to get directory specified by the source tfplan.json: relative paths require a module with a pwd.
Is this an expected behaviour? If yes, can we make the error message more user-friendly?
