Where does the bug appear (feature/product)?

Background Agent (GitHub, Slack, Web, Linear)

Describe the Bug

On weekend I uninstalled Cursor from github organisation, but I only wanted to disabnled Cursor Bugbot, not the Agent.

Anyway I added the Github access to the organisation this morning again but it fails to list branches from the main repo !

I see http error 500 which points to application failures on your http backend:

page-6c53585d1beddfc3.js?dpl=xxx:1
POST https://cursor.com/api/background-composer/get-repository-branches 500 (Internal Server Error)

Steps to Reproduce

Add github, then remove it, add github again

Operating System

Windows 10/11

Current Cursor Version (Menu → About Cursor → Copy)

hi @alorbach can you go to Dashboard > Integrations > Github > Manage then select there which repo’s you want Agent to access. Sometimes reconnecting helps.

Let me know if you set the right permissions.

Well it worked after 15 minutes.

But still erhttp error 500 can not be a good sign from the backend

Ok I will check it again and provide details to our team.

The error you received was from Cursor Web or when launching Background Agent from IDE?

It was from background agent web, on Desktop Cursor Client I got other errors.
I think you should be able to reproduce with the steps described above.
