I created a CloudFormation stack using the template below via Boto3 Python method `cf_client.create_stack(StackName="test")`; however, when I attempt to call `s3_client.get_bucket_policy(Bucket="my-bucket")` I receive a `NoSuchBucketPolicy ... The bucket policy does not exist` error. 

```yaml

                  - "http://example.com/*"
```

Is this something that's supported? 

Thanks in advance.
