Why does Graphql return undefined if everything in console.log has data?

Question

Node.js

Good afternoon, there is a Resolver in which there is a Query. It is required to search for a restaurant by id
and if, for example, we insert such a code, everything works fine

Restaurant: async(parent, args) => {
      return await Restaurant.findOne({_id: args.id})
    }

However, if I add the populate and execPopulate methods, I get undefined on the front

Restaurant: async(parent, args) => {
      const items = await Restaurant.findOne({_id: args.id})
      const populatedItems = await items.populate('kinds').execPopulate()
      return populatedItems
    }

If you do console.log(populatedItems) there is an object with the necessary data, and the populate method worked just as well. as far as I noticed from more than 2 hours of testing, GraphqL stops working when the populate method comes into play

Answer 1

I found an error, the fact is that in Type I determined that I only get ID and therefore when I received the kinds object instead of id there was an error. It was necessary to fix in Type and query
