Hi
Please show me your project's folder structure (just the top-level files and folders) and your package.json contents here

Did you configure your Railway project's root folder to be backend?
By default, Railway runs from the root of the repo, so if your Express app is inside the backend/ folder, you'll need to either set the root directory in Railway to backend, or move the app files to the project root.
