Installing Cloud Code in VS Code

Trying to add the Cloud Code extension inside VS Code but getting errors when building. Looks like the extension has multiple files in the zip root, or something. How can I resolve this without upstream changes?

      name = "cloudcode";
      publisher = "googlecloudtools";
      version = "2.0.0";
