Error when inserting a document into MongoDB via Node.js

Question

I\'m trying to insert a document into MongoDB in Node.js. I have read from the DB successfully, and added documents via the command-line interface. However, I can\'t insert

You need to provide a callback function to your insert call so that the method can communicate any errors that occur during the insert back to you.

db.collection("test").insert({ str: "foobar" }, function (err, inserted) {
    // check err...
});

Or, if you truly don't care whether the insert succeeds or not, pass a write-concern value of 0 in the options parameter:

db.collection("test").insert({ str: "foobar" }, { w: 0 });
