Turns out, our problem is due to Sentry Web Worker having problem accessing our artifact stored inside our main Sentry container.
We got it to work by following jonaskello’s suggestion Improve source scrape debugability · Issue #4168 · getsentry/sentry · GitHub
The solution is to have both the main sentry container and all worker containers map the path
/var/lib/sentry/filesto the same volume so the files are shared between main and worker containers.– jonaskello
Prior to this our Sentry server is showing an IOError > [Errno 2] No such file or directory: xxxx.
