Hi,
I’m working in a PoC to prove that we can use Keycloak to hide the complexity of using multiple IdP such as Auth0, Microsoft 365, Google, AWS Cognito.
The problem is that although I could easily configure Microsoft and Google following the guidelines within Keycloak’s documentation, I’m facing some problems when it comes to setup AWS Cognito as an IdP through OIDC.
https://docs.aws.amazon.com/cognito/latest/developerguide/cognito-userpools-server-contract-reference.html states which endpoints and even which configurations should I be using to setup Keycloak properly.
I even managed to get the proper redirect and authentication using Cognito, but when the redirect from Cognito with the token happens, I get this exception from Keycloak:
09:36:59,472 ERROR [org.keycloak.broker.oidc.AbstractOAuth2IdentityProvider] (default task-43) invalid_request for broker login oidc
09:36:59,474 ERROR [org.keycloak.services.error.KeycloakErrorHandler] (default task-43) Uncaught server error: java.lang.NullPointerException

If it helps, I can provide the exported helm.
Does anyone know if it is possible to integrate with AWS Cognito using OIDC and if so, how (or what am I doing wrong)?
Thanks in advance,
Daniel.
