Preparing deployment to CapRover...

You are not in a git root directory: this command will only deploys the current directory.
Run "caprover deploy --help" to know more deployment options... (e.g. tar file or image name)

I forgot to write

- name: Checkout
        uses: actions/checkout@v2

Sorry for the disturbance.

@Alwinator having this issue myself-- I've added the checkout action, but what does the rest of your action look like, if you don't mind sharing.

This is my full workflow. It runs on all branches if the commit message does not start with WIP, but only deploys the main and release branches. First, it tests my NodeJS application, and if the tests succeed it deploys the main branch to my preview Caprover app and the release branch to my production Caprover app.
