I want to pass a certain string stored in my .env file to an @EventPattern() method decorator.

I understand that I cannot use ConfigService there because @EventPatter(<in_this_place>) this is not available.

I tried using process.env but it also doesn't work. What is the way to achieve this?

IF you really want to to use env variables inside decorators, then in the main.ts the very first lines must be

import { config } from 'dotenv';
config()

This is before all other imports as well. This will populate process.env for you
