Error tracking does not error when given invalid API key

I just setup a sentry error tracking test project and modified the API key to something fake.

I expected to see the error state when loading the error tracking view. Instead, I just saw the loading spinner and the website kept polling for the error tracking list.

Steps to reproduce

1. Create project on gitlab
2. Click enable error tracking in Operations -> Error Tracking
3. Fill in https://sentry.io/api/0/projects/clement-0o/test/ for API URL, and google as the Auth Token
4. Go to Operations -> Error Tracking
