I have a CloudFront distribution in ap-souteast-2. Which is associated with an ALB. Both these resources are created using Cloudformation. I have associated a WAF with cloudfront with the scope of the WAFv2 as cloudfront. I am deploying this in us-east-1. Upon deploying the WAF code in us-east-1 , I noticed the following error.

Resource handler returned message: "AWS WAF couldn?t perform the operation because your resource doesn?t exist. (Service: Wafv2, Status Code: 400, Request ID: 7165d5e9-aa1d-4057-a5f2-b6a5617cbbdf)" (RequestToken: 82863340-6852-b176-023f-01beb14f28b1, HandlerErrorCode: NotFound). How do I then associate this WAF with a cloudfront deployed in ap-south-east 2 can exports be done cross region in cloudfromagtion…i think not right?

Here is my WAF code. Can you help me troubleshoot this as its a pretty generic runtime error.

    MyCloudFrontDistribution:
        Type: 'AWS::CloudFront::Distribution'
        Properties:
          DistributionConfig:
            Enabled: true

            - DomainName: !ImportValue my-ApiGatewayDnsName
              Id: testgwy
              CustomOriginConfig:

              MaxTTL: 300
              ForwardedValues:
                 QueryString: true
              TargetOriginId: testalb
              ViewerProtocolPolicy: allow-all
            WebACLId: !Ref MyWaf

Thanks

I tried putting the cloudfront and WAF in us-east-1 but then the cloudfront deployment failed as the origin it links to is in ap-south-east-2. I tried running WAF code alone in us-east-1 and got the error.

Update 1: I removed all the rules and tried it again and the WAF code worked..then included only commonruleset rule and itfailed..it think something to do with ruleset

The rule names were incorrect and I have corrected them and the code works now :) Thanks to all those who saw my question and also attempted to answer it!

    Your WebACL is called MyVicWaf, but you are using !Ref MyWaf. Also you need ARN, not Id. Thus it should be:

    WebACLId: !GetAtt MyVicWaf.Arn
