What issues are you running into exactly?

I deployed a REST API built in NestJs, it supposed to be connected to a PostgreSQL database. The build and deployment phases are successful, but from the nestjs perspective, I'm not able to access the service using the railway URL and Service is not able to stablish the connection to the database. PostgreSQL says "Database does not exists".

Have you setup all the needed environment variables?

I'm not sure what are all the required environment variables, it might be the problem.

Where do I find information about these environment variables?

You need to add the applicable environment variables that your app needs.

This is the list, Am I missing something?DB_HOST

DB_PORT

HOST

PASSWORD

PORT

USER_NAME

These are not all environment variables for a database.

I would recommend using DATABASE_URL

Yeah, but what if I don't need this URL to run my service in local environment? Does railway uses this URL in order to work properly?

Do you have a NestJS Stater kit that I could check?

Your code would need to use it to connect to the database.

I'm using TypeOrm, just the connection string parameters are mandatory.

I saw the problem, there was a mismatch between the name of the environment variables name provided from railway, and the environment variables that my service is using.
