'database name must be a string' Error when connecting with my Connection String

Question

I am attempting to connect to MongoDB via the package mongoose, but get an error along the lines of MongoError: database name must be a string.

I am using Windows, within the script I am also connecting to 2 other APIs which are both connected. I have tried adding my database name when requiring mongoose and also when connecting (.MyDatabaseName to the end).

Mongoose.connect("mongodb+srv://MyUserName:[email protected]", {useNewUrlParser: true}).EternalsMilitary;

Mongoose.connect.once("open", function() {  
    console.log("Connected To MongoDB");
}).on("error", function(err) {
    console.log("Error Connecting To MongoDB: ", err);
});

It's expected to output connected, but it errors with MongoError: database name must be a string.

try this: mongoose.connect('mongodb+srv://MyUserName:[email protected]/', {dbName: 'yourDbName'}); Adding the dbname since you're using the mongodb+srv syntax — dillon.harless

I needed to include the database name inside of the URI string. For example... mongodb+srv://MyUserName:[email protected]/MyDatabaseName This will then point it to that specific database.

For whatever reason the new url parser doesn't seem to work with certain URLs.

As a quick fix you can try reverting back to the old one with { useNewUrlParser: false }

I already have a fix, using the new URL parser. Thanks anyway though

@William please do share your fix, if you have time :-)

I apologize, should I put it in this comment section?

@William it's possible to answer your own question, that would be a great :)

connection works, but throws deprecation warning saying it should be true

In your URI after where it says mongodb.net put slash and the name of the database for example:

mongoose.connect('mongodb+srv://<username>:<password>@<instance>.mongodb.net/**nameDatabase**', {dbName: "Eclipse"}, {useNewUrlParser: true})

Aside from replying to a question over 2 years old, please don't propagate credentials (those are "live" creds - I tested). I edited them out of your answer (though anyone with enough rep can see them)

I just copied them from the comments above as an example and wanted to explain it in a different way for other people to see this, I didn't think anyone would be offended

Also I'm new and I can see them so anyone can see them

This has nothing to do with being offended. The OP made a mistake, publishing real credentials in a comment (if it was in their original question, I could have easily edited them out). This is something to be aware of in the future, to ensure you never re-broadcast such a thing. As I already said, I took care of it. And as far as who can see your answer's history: only people with several thousand rep points can see the edit history and non-edited username/password (not talking about you, as you are the author of your answer).
