Describe the bug
When running npm start in the /server folder, I get the following error:

2024-11-27T16:06:12.866Z: error: Error connecting to QRev Analytics db cluster:  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.
 Stack: MongooseError: 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.

To Reproduce
Steps to reproduce the behavior:

1. Follow set up steps
2. Make sure a database is created and the connection string is correct
3. Enter the connection string in the env file under MONGODB_URL
4. run npm ci followed by npm start, the error comes up

FYI, this can be fixed by adding the following to the .env:

QREV_MONGO_DB_2_URL=

I recommend making a new db for this as well
