Additional info

Building the docker image locally from the aforementioned build context works (docker build -f ./apps/demo-app/Dockerfile .). My gut feeling is that somehow build-push-action is reading the path provided to the COPY command as absolute rather than relative to the path context.

Update: Somehow, the file sytem on the Github action went nuts, and couldn't see the file. This is why it worked locally. I renamed it and the Github action is working now.
