AWS SSO and AWS IAM Issues

Hi,

I am trying to configure Auth0 as an IdP For my AWS Account(s). I have been successful in adding Auth0 as the IdP and can access AWS with the correct role and correct permissions when I used the login URL that is on the SAML-Addon Page.

However, my dev workflow includes using Granted and that uses the specific AWS Identity Manager (Formerly AWS SSO) Url which is of the format https://<account_id>.awsapps.com/start. If I use that URL, it does a few redirects, eventually landing at my Auth0 Application’s login page where it shows an error page (Screenshot attached).

The three topics I see about this are all from 2020 or before and do not have the information I need.

My question is:

  1. Why am I getting that error?
  2. Can it be fixed?
  3. What Can I do to fix it if it can be fixed?

Thanks.
