title: 5005: attachment source fetching is temporarily unavailable | API Docs
description: attachment source fetching is temporarily unavailable
---

attachment source fetching is temporarily unavailable. This is an HTTP 502: a dependency we call failed.

## Troubleshooting

- Check the file against the documented size and format limits for this field.
- For a source URL, confirm it is reachable, returns the declared content type, and is not behind auth.
- Storage and fetch failures are transient: retry with backoff before treating the attachment as bad.
