Cognito user pool client issues.

Amazon Cognito is a powerful identity service that enables secure user sign-up and authentication, but configuration errors and client issues in Cognito user pools can prevent users from logging in or accessing protected resources

In this blog, we highlight common Cognito user pool client issues and how Informatix Systems helps businesses troubleshoot and resolve them

Common AWS Cognito User Pool Client Issues

Invalid Client ID or Secret
Using the wrong client ID or forgetting to enable the client secret can cause failed login attempts and authorization issues

Callback or Logout URLs Not Set Correctly
Improperly configured redirect URIs prevent Cognito from completing the authentication process

Unsupported Authentication Flows
If the user pool client is not set up with the correct auth flows, such as USER_PASSWORD_AUTH or ADMIN_NO_SRP_AUTH, the login request will fail

Token Expiration or Invalid Scope
Clients must request the correct scopes and handle access and refresh tokens properly to avoid session errors

CORS or App Integration Issues
Missing CORS settings or incorrect JavaScript integration can block web apps from communicating with Cognito
