Missing Package Dependencies: Identified that the server entry point server.ts was importing cors, but neither cors nor @types/cors was declared in your package.json file. Since the build environment bundles the server with external packages, this resulted in runtime crashes. I installed both packages and updated the dependencies list. Server Bind Address: Standardized the Express server's listening configuration to cleanly bind to host "0.0.0.0" on port 3000 for perfect ingress routing within Cloud Run.
