MongoDB Stitch throwing anon-user error

Question

I am using mongodb's stitch backend to run an application, and when I try to login as an anonymous user, it throws this error:

failed to log in anonymously: { StitchError: authentication via 'anon-user' is unsupported

at process._tickCallback (internal/process/next_tick.js:160:7)

_raw:
[ ],
_abort: false,
_bytes: 57 },
json: { error: 'authentication via \'anon-user\' is unsupported' } }

Items marked with ***** were removed for privacy.

I have anonymous authentication enabled in Stitch Admin Console, but it still throws this error. My app is not even able to perform any operations on the database before this happens, so I know it does not have to do with my app's Rules.

Is there something I don't know about anonymous auth?

If you know where the mongodb error reference is, that would help as well.

Thanks

Answer 2

You need to go Stitch Apps > Users > Providers > Allow users to login anonymously and enable that option.
