Error message
Error Details: %v
What it means
Final diagnostic in buildVFSPath after the URL was recognized as neither S3 nor GCS nor a pass-through scheme: the command prints detailed guidance (S3/GCS/path requirements) and then fails with this generic 'Error Details' message. The target file repository URL is unsupported.
