MODULE_NOT_FOUND

A MODULE_NOT_FOUND during docker cp command #228 can happen if you are relying on local changes that have not been pushed. This can get triggered if the action is using a path, like:

- name: test action locally
  uses: ./

In this case, you must use actions/checkout@v2 with a path that has the same name as your repository. If your repository is called my-action, then your checkout step would look like:

steps:
  - name: Checkout
    uses: actions/checkout@v2
    with:
      path: "my-action"

If the path: value doesn't match the name of the repository, a MODULE_NOT_FOUND will be thrown.
