failed to get file URL: %w

Error message

failed to get file URL: %w

What it means

Thrown inside generateFailedEntriesCSV when fileSvc.GetFileURL fails to mint a download URL for the just-uploaded failed-entries CSV. The file exists but is unreachable via presigned URL; typically a signing/endpoint configuration problem in the file service.

Solutions

1. Verify storage endpoint / presign configuration for the temp bucket
2. Check credentials and clock skew affecting signature validity
3. Retry; the CSV object itself was already saved and can be re-URLed
