As the error message states, you need to make sure that you pass a string of the database URI to mongoose.connect(). You can obtain the database URI by going to your MongoDB cluster on the MongoDB website and clicking Connect. The URI should start with this:
mongodb+srv://<db_username>:<db_password>@<cluster_name>...
In your call to mongoose.connect(), include the URI like so:
await mongoose.connect('<your database URI here>');
