Cannot integrate Bitcbucket

Trying to integrate Bitbucket and Sentry. In the authorisation page for bitbucket, after clicking “Grant access”, I am given this URL:
Additionally, it gives a HTTP error 405.
Notice in the URL, it is an error with Sentry, not Bitbucket.

in the meantime, it seems like sentry isn’t finding the commits from my latest release with bitbucket using the release api.

Might be something related to the recent changes from bitbucket

Maybe the same as Bitbucket repository integrations is gone?
