    hey it happens - hopefully you have good rollback policies so you can add test coverage, bug fix and redeploy.

    Happens way too often. Probably it's time for a production environment clone to do the integration testing on.

    @binhex I created a new branch with git from the latest commit I knew was stable, then pushed to origin and commanded the backend to update from that branch while I fixed it.

    @youprat unfortunately I can't clone the production environment since it relies on OAuth2 user consent.

    @Frederikam Yeah that's a little tricky when you're delegating authentication to something like OAuth2.. You could generate fake user tokens and mock your OAuth calls to verify the fake user tokens.
