Reference problem

Hi Mike, try this:

const threads = await wixData.query("threads")
   //take out the _id value of the first item in the array 
   //and use it to find the threads that belong to that forum
  .eq("forumId", forums.items[0]._id)
  .find();

note that in as far as what is stored in a collection for a reference field, we only store the _id of the target object.
so you need to use that _id value in your query filter.

hope this helps and let me know if you need more info on how references work in wixcode.
