title: 5002: attachment source returned an empty body | API Docs
description: attachment source returned an empty body
---

attachment source returned an empty body. This is an HTTP 422: the request parsed but a value is not acceptable.

## 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.
