Create CLOUDFRONT scoped AWS::WAFv2::WebACL with CloudFormation

Question

Hi!

I'm having difficulties creating a AWS::WAFv2::WebACL resource with CloudFormation:

The documentation (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-wafv2-webacl.html#cfn-wafv2-webacl-scope) states *For CLOUDFRONT, you must create your WAFv2 resources in the US East (N. Virginia) Region, us-east-1*.

The only WebACL resource I am trying to spawn basically looks like this: 
```
  ExampleWebACL:
    Type: AWS::WAFv2::WebACL
    Properties:
      Name: example-name
      Description: example-description
      Scope: CLOUDFRONT
      DefaultAction:
        Allow: {}
      VisibilityConfig:
        SampledRequestsEnabled: true
        CloudWatchMetricsEnabled: true
        MetricName: example-metric
```
Creation fails for `Scope: CLOUDFRONT` with `400 / Error reason: The scope is not valid`.

Where do I set the region to `us-east-1`?

Thanks
Christoph

Answer

Thank you aabragan for hinting at what the solution is: `--region us-east-1` does the trick.

I guess
* the first statement is, that CloudFormation stacks are region bound
* and the answer to the question *how do I create resources in multiple regions* may be StackSets.
