BitBucket is not yet supported by Netlify CMS. You can follow #234 for updates!

I just had this same issue using GitLab repo + Netlify Identity. I didn't invite a user like the OP. I just created my own test account, got the email to confirm my email address, confirmed, then I was redirected to the login screen and got the same exact JSON error message.

The console error message says there is a 404 GET request error for retrieving https://[mysite].netlify.com/.netlify/git/settings.

The error message only appears if I am logged in as the test user. If I open the /admin/ URL in a fresh incognito window (not logged in), I don't see the message, but after I log in, it'll say I have logged in and nothing happens except it says I'm logged in and there is a button to log out or close the login confirmation modal. If I refresh the page, it'll show the error again.

Sorry, disregard! I had enabled git-gateway via my config file and had enabled Identity in Netlify but had not enabled Git Gateway per the docs (https://www.netlify.com/docs/git-gateway/#getting-started). Sorry about the false alarm!
