Issue details

When updating AWS Cognito User Pool (i.e. pulumi up for the second time) without changing anything, it errors out:

* error updating Cognito User Pool (us-west-1_xxxxxxxxx): cannot modify or remove schema items

I also noticed that Cognito IdentityProvider resource also shows diffs, even though nothing was changed in code:

[diff: ~attributeMapping,providerDetails]

Steps to reproduce

1. Create a Cognito User Pool via classic AWS package (i.e. new aws.cognito.UserPool())
2. Run pulumi up
3. Run pulumi up again without changing any code

Expected: pulumi up should complete with no changes and no errors when no code is changed
Actual: It errors out instead: * error updating Cognito User Pool (us-west-1_xxxxxxxxx): cannot modify or remove schema items

Hi there! This appears to be an upstream bug:
hashicorp/terraform-provider-aws#21654

OK thanks. So just to confirm - nothing we can do but wait til that upstream issue is fixed?

The upstream bug has been closed. We should test to verify that this is no longer an issue. cc @mikhailshilkov

Verified that there is no longer an error generated with AWS 5.42.0.
