I created a serverless App on AWS using the serverless framework template. The Lambda function is in python3.10, arm architecture. the code will register an user in aws cognito user pool. I created a cognito user pool and cognito user pool client. The lambda handler has the cognito policy to create the user using the admin create user, admin_initate_auth, respond_to_auth_challenge functions. im am not understanding why the lambda is getting timed out. the lambda is running but it is not executing the code client.admin_create_user() function.
