• What is the current behavior?
  The linter is currently showing an incorrect error on a AWS::ElasticLoadBalancingV2::Listener configuration.
  

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via

Create a AWS::ElasticLoadBalancingV2::Listener with 2 default actions. A possible example is the configuration below:

  LoadBalancerHTTPSlistener:
    Type: AWS::ElasticLoadBalancingV2::Listener
    Properties:
      LoadBalancerArn: !Ref LoadBalancer
      Port: 443
      Protocol: HTTPS
      Certificates:
        - CertificateArn: !Sub 
            - "${LoadBalancerCertificateArn}"
            - LoadBalancerCertificateArn: {"Fn::ImportValue": !Sub "${ParentStack}-LoadBalancerCertificateArn"}
      DefaultActions:
        - Type: authenticate-cognito
          Order: 1
          AuthenticateCognitoConfig:
            UserPoolArn: !GetAtt UserPool.Arn
            UserPoolClientId: !Ref UserPoolClient
            UserPoolDomain: !Ref UserPoolDomain
            Scope: 'openid email'
            OnUnauthenticatedRequest: 'authenticate'
        - Type: forward
          Order: 2
          ForwardConfig:
            TargetGroups:
              - TargetGroupArn: !Ref TargetGroup
                Weight: 1

• What is the expected behavior?

The expected behaviour should be no linting errors, since i was able to upload and deploy the CloudFormation as is.

Also, this was already corrected in other plugins, as seen here

• What is the motivation / use case for changing the behavior?
  N/A

• Please tell us about your environment:

  • Plugin version: 0.5.24
  • VSCode version: 1.40.2
  • Template type:

AWSTemplateFormatVersion: '2010-09-09'

• Other information (e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. stackoverflow, gitter, etc)

If you wish, I can provide the Full Template in the thread.

I believe the issue with this plugin is similar to this: aws-cloudformation/cfn-lint#1251

thanks for reporting @plinioh!

The plugin uses cfn-python-lint output to display errors. Please follow the solution that described here aws-cloudformation/cfn-lint#1251
