Hello again Allen,
I’ve just gone through the instructions again, and they work fine for me. I think the script is talking about definitions for the DB objects taken from the model, rather than the routes, so I don’t think that’s an issue.
One thought I had - did you save the script in the right place? The instructions were a bit unclear, so I’ve rewritten them slightly. To be exact, the script should be saved in the same directory as the package.json file.
1. Did you create all four models as directed?
2. Did you install async as directed?
3. Check your code against the example repo at https://github.com/mdn/express-locallibrary-tutorial

I ran into some problems at the end of part 3, where you run the script to populate the database. I downloaded the script, ran it and only got the authors inserted into my database, nothing else. I got these errors on the command line:

At this point in the tutorial we built routes for /, /users, and /users/cool, so according to how I understand things, nothing should have worked. I also didn't get an error for 'bookinstance' but they weren't inserted into the database either. Can anyone shed some light on what is going on?
