Hi Jay,
Thanks for the reply.
To clarify.
The flow on our app (not discourse) is passwordless - user enters email → receives a 6 digit code in email → enters code → signs in
To enable this we have lambda triggers that define/create and verify the auth challenges. Further, the ui is custom (i.e. not provided by aws amplify)
What we want is the discourse sign in process to be the same. I attempted to use the same cognito app client configuration for discourse but get this error page
(the network call isn’t very helpful from cognito about this error)
