I have the following on my AWS CodePipeline Cloudformation template:

Variables:
    - Name: VARIABLE_NAME
      Description: Some description
      DefaultValue: ""
Version: 2

When I create the CodePipeline using Cloudformation, I get the following error:

Resource handler returned message: "Pipeline variable can only be used with V2 pipelines"

I am also getting the following error when I do it manually on the UI:

Any idea what I’m doing wrong or is it an AWS issue?
