Welcome, jhaycawasa.
I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.
See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.
Note: Backticks are not single quotes.

To help your question: If you have run the script to create a model, and it was not 100% correct to begin with, then your database has an incorrect collection, and you could try:
- Going into your Mongo account, and clearing all records.
- Re-running the tests/script.
Or
- Go back to the first challenge, and concurrently complete all of them again.
Hope this helps
