Hey 
Thank you so much for this post
I tried to follow along with your post, however, I wanted to use terraform, I did the best I could to implement it.
But now it cognito only calls the token endpoint but never retreives the user from the user endpoint.
Could you give me a hint on how to debug this, the logs from cloudwatch and cloudtrail simply work till the call of the token endpoint and then stop… ?
