I have a successful OAuth flow working, however, when going through the flow with Google it is showing, do you want to authorize amazoncognito.com, instead of my domain name. I tried using the CLI "amplify auth update" but that doesn't let me specify a custom domain. Is there a way to specify that custom domain outside of manually in the AWS console?

This temporary workaround will allow me to not lose updates to aws_exports:

import aws_exports from '@/aws-exports'

var my_exports = JSON.parse(JSON.stringify(aws_exports))
my_exports.oauth.domain = 'auth.mysite.com'
Amplify.configure(my_exports)

Testing this, but I believe this will work.

When you do amplify auth update, did you select Walkthrough all the auth configurations? This should have you step through all configurable values, and will lead you to a question about OAuth flow. If you say 'yes' to the OAuth question, the CLI will subsequently show a question asking you to enter your domain.

I do get prompted for a "name", but it's not a domain name, the CLI makes the OAuth endpoint something like "mysite-beta.auth.us-east-1.amazoncognito.com". I would prefer instead to simply have "auth.mysite.com". I can only do that by manually configuring awsexports and setting the custom domain in Cognito.

@cliffordh Unfortunately, Cognito appends the "auth.us-east-1.amazoncognito.com" domain to your provided domain name - which is the behavior on the cognito console as well.

@cliffordh works for me .. really wish there was a way to specify the full domain not just prefix in settings to avoid this hacky method for something fairly common ..
