Recently, I faced the same issue and later I realized that I forgot to require .env configuration.

Error

TypeError: OAuth2Strategy requires a clientID option

Fix

npm i dotenv

and then require it at the top of your file

require(dotenv).config()

The issue is caused because your server has no idea that it has to use the environment variable.
