Firebase cloud function cannot read .env variables

Question

I followed this doc and added .env file with variables in a Firebase Cloud Function project.

When trying to deploy, I get this message: Loaded environment variables from .env.

However, it is always undefined when I try to use process.env.ENV_VAR. Am I missing something?

I'm using firebase-cli 11.0.1 and firebase-functions 3.21.2

Answer 1

I used env variables for firebase credentials. Seems like it was loaded before env var. So my solution is to use firebase function config
