Whenever I try to upload an image I see a progress indicator underneath the image, but then a popup appears with the unhelpful message “An error occurred while uploading your asset.”
Looking at the console there seems to be a CORS problem:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://o2239.ingest.sentry.io/api/<redacted>/envelope/?sentry_key=<redacted>&sentry_version=7. (Reason: CORS request did not succeed). Status code: (null).
I’m using Firefox 101.0.1 (64-bit) on Linux. Uploading does work in Chromium 103.0.5060.53.
This user seems to have had the same problem almost a year ago (it’s marked resolved, but I think they just switched browsers?):
