[Feature Request] - Enable custom domain

[mazzolia-prom]

Describe the bug
Hi,
we are trying to set up an amplify custom domain, to serve as frontend but we can't figure out.

To Reproduce
We created the amplify domain and associated to the amplify app

we set up the Identity center APP

Application start URL = https://d140lbzcafqm2w-prod.auth.eu-west-1.amazoncognito.com/authorize?client_id=1prrp5ip6hno5l3qb96vomrauc&identity_provider=IDC&response_type=code&scope=aws.cognito.signin.user.admin+email+openid+phone+profile&redirect_uri=https://team-request.prometeiasaas.com/&idp_identifier=IDC

but on click

the redirect uri specified in the Application start URL goes to the Amplify default domain instead the custom domain

this is the cognito application web client

Expected behavior
cognito redirect to the custom domain

@mazzolia-prom can you try removing the default amplify domain from the allowed callback URLs and retaining only your custom domain ?

[EGHPrometeia]

@tawoyinfa I have the same problem. I tried to remove the default amplify domain from the allowed callback URLs, retaining only my custom domain. If I try to access the app from SSO, I am redirected to my custom domain. Nevertheless, I receive a 400 error ('configuration_mismatch') when I click on the 'Federated #' button.

@EGHPrometeia did you update your Application start URL in the Identity center configuration for the TEAM application to reflect your custom domain ?

[EGHPrometeia]

@tawoyinfa yes, we updated the Application Start URL as follows:

https://d140lbzcafqm2w-prod.auth.eu-west-1.amazoncognito.com/authorize?client_id=1prrp5ip6hno5l3qb96vomrauc&identity_provider=IDC&response_type=code&scope=aws.cognito.signin.user.admin+email+openid+phone+profile&redirect_uri=https://team-request.prometeiasaas.com/&idp_identifier=IDC.

As you can see we updated it with our custom domain name.

Thanks
