Reddit media upload did not return a location

Error message

Reddit media upload did not return a location

What it means

RedditProvider.uploadFileToReddit parses the S3 upload-part XML returned by Reddit's upload lease endpoint for a <Location> tag; when none is found it throws this BadBody with the raw response. Without the Location the multipart upload target is unknown, so the media upload cannot proceed.

Solutions

1. Inspect the raw body included in the error (d.data) to see what Reddit actually returned
2. Re-authenticate the Reddit integration (expired tokens often yield error JSON)
3. Confirm the media mimetype is supported for Reddit uploads
4. Check Reddit API status / version for upload lease contract changes

catch (e) { if (e instanceof BadBody && /did not return a location/.test(e.message)) { /* log d.data body, re-auth */ } }

When it happens

Trigger: Reddit's api/media/asset endpoint returns a body without <Location>...</Location> — expired lease, unexpected error JSON, or Reddit API change; also when d.data is empty.

Common situations: Auth/session issues making Reddit return an error body instead of the lease XML, Reddit API contract change, or mimetype not covered by the asset lease.
