Hello fellow infra engineers, I’m currently setting the Cognito auth service and I want to use the COGNITO_USER_POOL I’ve created, as the default identity provider.
Under, " aws_cognito_user_pool_client, I’ve tried using “supported_identity_providers = [aws_cognito_user_pool.user_pool.id]” and ‘user_pool.name’ and they both failed with “InvalidParameterException”
I’m quite proficient in reading TF’s doc, but I could only find reference to https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/cognito_identity_provider , which is meant for 3rd party providers, i.e Facebook or Google.
I did found this old post from Google Groups saying TF didn’t support setting the user_pool as the default identity provider:
https://groups.google.com/g/terraform-tool/c/luTSsPuXUu8?pli=1
is this really the case now? do i really need to deploy the app and then go to the browser to check one checkbox? i’m using TF 1.04, which is awesome 
thanks,
Elad
