My .env file code is below:
SECRET_KEY=super_secret_key_you_should_change

MFLIX_DB_URI=mongodb+srv://mdnadim:hiddingpasswoard@cluster0.rydkou5.mongodb.net/sample_mflix

MFLIX_NS=sample_mflix

PORT=5000

and my index.js file code is below:

require("@babel/register")
require(".env").config()

exports = module.exports = require("./src")

Can you tell me where is the problem? Thanks in advance
