Describe the bug
I am trying to deploy any service via AWS service broker (I've tried a Kubernetes and Tanzu Application Service, result is the same).
CloudFormation stack goes fine until the creation of two custom resources: AWSSBInjectedGetCidrs and AWSSBInjectedGetAzs.
Then they just hang for a very long time until the timeout error.
To Reproduce
Try to deploy any service via AWS service broker.
Expected behavior
Service is successfully deployed by AWS service broker.

Environment (please complete the following information):
- Application Platform: Tanzu Application Service, Kubernetes
- Application Platform Version: TAS v2.12.1, Kubernetes v1.21
- Broker Version: 1.0.4
