Hi there. I’ve edited your code for readability.
When you wish to post code on the forum please use the Preformatted Text Tool (</> icon or CTRL+e) and paste your code between the two sets of triple backticks.

Did you have a particular question about this code? Could you post a link to the challenge which you’re stuck on please?

The version of Mongoose you are using does not support callbacks anymore. Refactor the code or downgrade the version.
