I am trying to create a Cognito User Pool and I want it to be able to publish to an sns topic to send SMS messages. My main problem is that when I am trying to bound the resources on the sns topic policy document I am getting this error

I am new to Cognito and hope I’m not missing something obvious here. I tried created a user pool and hosted UI via Terraform. Upon creation, the hosted UI is completely blank. Auditing the network calls reveals several failed GET requests for resources.
