I'm getting the above issue when I'm using the env variables mentioned in the workflow. And here is my workflow

# This workflow will do a clean installation of node dependencies, cache/restore them, build the source code and run tests across different versions of node

What is the correct way to use these variables here?

The Context being used by the workflow is not the .env in the host machine; when you set those commands. The variables must be on from the workflow context as secrets or inputs.

${{ secrets.REGISTRY }} - The syntax is the same as you did for the host, username, privateKey, passphrase.

I can confirm this because one of my commands uses the ${{input.key}} which is derived from the Repo Name to cd into the respective directory.

i.e.
command: cd ${{inputs.directory}}
