Deploy fails when adding Cognito requiredAttributes as per documentation

The CDK documentation shows how to add required attributes to the Cognito user pool. However, when implemented as per the documentation, the deploy fails. Removing the the requiredAttributes property results in a successful build.

Reproduction Steps

new cognito.UserPool(this, `${id}Pool`, {
  requiredAttributes: {
    email: true,
    fullname: true,
  },
  selfSignUpEnabled: true,
  signInAliases: {
    email: true,
    username: false,
  },
  userPoolName: `${id}UserPool`,
})

This is 🐛 Bug Report

The Cognito service limits that required attributes for a UserPool cannot be modified after it has been created. It turns out this is the error message they throw when this is performed.

I was able to create a new stack with a user pool with the configurations you have provided.

I was able to create a new stack with a user pool with the configurations you have provided.

Why is that? My stack depends on lot of other stack as well, so if I destroy cognito stack I need to destroy all the stack which it depends on.
