docker-compose up: FATAL: database "boilerplate," does not exist (Postgres Node)

Question

I am trying to connect a node server to a postgres database with node-postgres (pg). My docker-compose.yaml is below:

version: "3.7"
services:
  server:
    build:
      context: ./node-boilerplate
      dockerfile: Dockerfile
    ports:
      - '3000:3000'
    depends_on:
      - db
    environment:
      DB_USER: postgres
      DB_PASSWORD: postgres
      DB_DATABASE: boilerplate,
      DB_HOST: db
  
  db:
    image: postgres:latest
    container_name: boiler-db
    ports: 
      - '5432:5432'
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
      POSTGRES_DB: boilerplate

When the node app tries to access a database called boilerplate that actually exists, it gives the error:

FATAL:  database "boilerplate," does not exist

However, when I connect to the postgres container (using docker exec -it <postgres_container_ID> psql -U postgres) and list databases with \l, it shows the database boilerplate listed.

What am I missing? How come the database shows up but the node server cannot find it?

Thank you in advance.

Try to docker-compose up without comma:

  DB_DATABASE: boilerplate
