Hello Im trying to build a github action pipeline to automate the CI/CD of my repo, im doing a fork of the openproiect repo and in railway usuing the OpenProject image as this is for learning purposes, but at the time of the CI/CD I want this to be less manual between dev, qa and prod using multiple images accross projects.

At the time I'm getting an error with the pipeline as shown on the screen. What I want the pipeliune to do is build the service withe new image which I set on the variable SOURCE_IMAGE of the pipelinbe on the service. Is this possible? This is my source code (there is no problem in sharing as Im using variables and this is a uni project):
