Unable to Deploy Kong API Gateway with PostgreSQL on Railway

Question

We are trying to deploy Kong API Gateway (with a PostgreSQL database) on Railway using the following docker-compose.yml and Dockerfile. The setup works locally in Docker Desktop, but when deployed to Railway, the deployment fails. Below are the files we are using:
