[1] MONGO DB ERROR! Using in-memory DB - Not reliable!!

I have already set up the .env according to the .env.sample in the repo. Not sure why the database is not connecting. Can you help me here?

[muke1908]

@Shardul1908 probably wrong URI (wrong format)?
You should still be able to run the app even if no mongo db.

[sharduld1908]

Ohh okay, let me try that. Why is MongoDB used then?

[muke1908]

If mongodb is not configured, it'll use inMem storage. Not ideal but you'll be able to run the app. Mongodb is configured in production
