If you get this error even if your code is working fine locally, the answer could be that when you push to GitHub, for whatever Godforsaken reason, the .env file (that you changed from .env.example earlier) was pushed to the .gitignore file as text. DELETE THAT TEXT AND DO A NEW PUSH TO GITHUB AND VOILA.

Hope this helps at least a few, lol. Mad luv to the community builders! Thanks Alvinsga!! :)
