Good morning everyone,

I am currently working on a price search engine with NodeJS and Mongoose and have a question about the implementation of a price matrix.

I’m exporting data from an API to JSON files and importing them to MongoDB. My problem is that if I have an Object within the document I can’t write data to that Object and I can’t find what is causing the problem. From what I’ve read it’s possible to use Object type in a Schema but I can’t find a working solution, instead I have to completely restructure the JSON file to not include Objects.

In the user model, they have used userId a custom-generated ID (Cannot change now), but for my API, I want to user populate data with my return response, since the system uses userId instead of _id, I can’t map the populate correctly. So how do I populate data?
