How to properly deploy an App on digital ocean from DOCR using github actions?

I was looking at the documentation on this readme on how to deploy an app on digital ocean from DOCR using github actions, however, I still can not get it to work.

These are the two main configurations that I have tried and their results:

    - name: Deploy digital ocean app for server
      uses: digitalocean/app_action@main
      with:
        app_name: jujuserver
        token: ${{ secrets.DIGITALOCEAN_ACCESS_TOKEN }}
        images: '[{
                  "name": "jujuserver",
                  "image": {
                    "registry_type": "DOCR",
                    "repository": "jujuserver",
                    "tag": ""${{steps.github-sha.outputs.sha}}""
                  }
                }]'

Results in correct run of github actions and deploys the App, but does not update the code running in it with the new code in github. This also happens if I use the lates tag instead.

The other one is, following the docs:

      - name: Deploy digital ocean app for server
      uses: digitalocean/app_action@main
      with:
        app_name: jujuserver
        token: ${{ secrets.DIGITALOCEAN_ACCESS_TOKEN }}
        images: '[{
                  "name": "jujuserver",
                  "image": {
                    "registry_type": "DOCR",
                    "repository": "registry.digitalocean.com/juju/jujuserver",
                    "tag": ""${{steps.github-sha.outputs.sha}}""
                  }
                }]'

This results in the following failure from github actions and no deployment is made, but I do not know why it is failing:

Does anyone have a clue as to why this may be?
