Hello all. For VSCODE extensions, It does not look like all of the appropriate options are available via intellisense, and errors occur for those not included. For example including vars results in an error.:

  - put: cloud-foundry-g1
    params:
      vars:
        MYVAR: myvalue
      manifest: manifest.yml

This looks like where it would need to be added, although my familiarity with VS Code Extensions is limited.
