File has no storage path
Open/read or transfer failed because the file has no storage path (400 / job fail). Transfer jobs may note the upload was incomplete.
Why this happens
Upload never finalized, path not written, or broken file row. Distinct from empty S3 body (path present, object empty).
Diagnose and fix
1. Re-upload the file; confirm finalize succeeds (Could not finalize upload on storage server).
2. Do not transfer incomplete uploads.
3. Admin: inspect the file row’s storage fields.
4. See Invalid storage path.
