Node.JS Bizarre Node.js error

[DennisM]

I'm trying to do some basic stuff with MongoJS. When I try to run this simple program:

var database = "testingMongoJS";
var collection = "testCollection";

var db = mongojs(database, collection);

db.on("error", function(error){
    console.log("Database: ", error);

})

app.get("/", function(req, res){
    db.testCollection.find({}, function(error, found){
        console.log(found);

    })
})

I get this error:

What's the deal?

I think that collection with mongojs needs to be a collection, not a string or something.
You could also try to implement forEach function on collection but I think it needs to be a collection such as an array.
Try with database and/or colllection as an array or dictionary.

Best work around, although not as optimal: use vanilla for loop
