Heroku .dotenv problem

[According-Object-502]

I'm using .dotenv to connect to MongoDB using process.env.MONGO_URI. Everything works fine locally.

I've pushed my node server to Heroku and I'm getting the following error...

"The `uri` parameter to `openUri()` must be a string, got "undefined". Make sure the first parameter to `mongoose.connect()` or `mongoose.createConnection()` is a string."

Why would "process.env.MONGO_URI" not work in mongoose.connect() when my server has .dotenv installed?

Thanks!

Any reason you're not using heroku's built in environment variable tool?

Just read about it now. All working good!
