Hi, i’m having a problem with the first challenge of this lesson. I have already done everything but y still get this message.

</div>

Because I can’t give you a hint in any way to help, I’ll just say if you use MONGO\_URI you have to delete everything after the question mark.

If you don’t use that you need the question mark at the end of your connection.

I’ve answered this before and I’ll add I don’t know why the query makes it not work, but it doesn’t work with the query after the question mark.

Also never use quotes in the `.env` file.

With the little code of yours that I see, it’s a little hard to say. But the directions say " Connect to the database using mongoose.connect()".

The directions don’t say to use a variable.

I reinstalled all the dependencies and it no longer shows me the error, but I still fail the test.

Did you stop using the variable? Also, you can include a callback function to log an error or log you are connected. Like

```auto
... {useNewUrlParser: true},
  function(err) {
    if (err) { console.log(err); }
    else { console.log("Connected to db!") };
});

```

Then you will see the error or “Connected to db!” in your log.
