GitHub integration throws exception on GET /api/0/organizations/:org/repos

Struggling to understand why we can install the GitHub application, but when going to configure, the Sentry logs show an error in the python code. Here are our logs:

GitHub app settings:

User authorization callback URL: $url/extensions/github/setup
NO Request user authorization
Setup URL: $url/extensions/github/setup/
NO Redirect on update
Webhook Active, url: $url/extensions/github/webhook
SSL Enabled

The application can be installed, but when going to configure, while tailing the logs, we see the 500 on GET /api/0/organizations/:org/repos

Any suggestions? Looks like all our configuration files are set correctly.

Could it be that Sentry server failing to communicate with GitHub due to some firewall settings? Since your logs cut off the error message of the stacktrace, it is hard to say more.

Also, have you followed this guide: https://develop.sentry.dev/self-hosted/sso/#github-auth (or figured this out yourself from the config files?)

Interesting. I am exploring the network connectivity issue, but the guide you linked suggests (to me) there is only one configuration needed for a single GitHub application, for both OAuth && repository integration?

We have a GitHub OAuth application which is working as expected, users are able to login. But this did nothing for the GitHub repos integration itself.

Will update with more when I discover.
