Hello
This is my application.yml on a simple test application. The logs say the application cannot connect to the database. Can you please help me on how to proceed?
Thanks in advance
spring:
datasource:
url: jdbc:postgresql://${PGHOST}:${PGPORT}/${PGDATABASE}
username: ${PGUSER}
password: ${PGPASSWORD}
driver-class-name: org.postgresql.DriverThis is my ENV
{
"PGDATABASE": "${{Postgres.PGDATABASE}}",
"PGHOST": "${{Postgres.PGHOST}}",
"PGPASSWORD": "${{Postgres.PGPASSWORD}}",
"PGPORT": "${{Postgres.PGPORT}}",
"PGUSER": "${{Postgres.PGUSER}}"
}

As per the logs, this is the most important message:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaSharedEM_entityManagerFactory': Cannot resolve reference to bean 'entityManagerFactory' while setting constructor argument
Which usually means that the backend could not connect to the database. If i hardcode the postgres values in my local machine, it works. But if I export the variables and define them in my application.yml, it doesn't work

This wouldn't be an issue with the platform, it would be a misconfiguration, please research this error and apply the fixes suggested from sites like stack overflow.

I agree, it is not an issue with the platform. As I said, if I hardcode the values, they will work fine and the application connects to the railway postgres
Is there anything wrong with the way I've set up the variables? I'm asking here because this is a very simple example, and variable misconfiguration inside Railway is the only thing I can think of right now, since there's not much room to go wrong here with the application code.

I'm assuming you do have the needed variables set in the variables tab of your service?

I've added the variables that postgres exports into my application
Is this the right way of doing it?

Looks good to me, you just need to figure out why your app is not reading the environment variables.
Are you sure java does variable expansion when loading values from a application.yml file? or maybe you are not using the correct syntax?

I think I know why it's not working, spring can't read you .env files, you need to import it for the spring application.properties, you should
have:
spring.config.import: optional:file:.env[.properties]It'll probably work. You need to have the .properties, didn't really read to much about it but I'm pretty sure it's related to the file extension.
