Collection Hook error but there's no hook whatsoever

Hook afterQuery for collection productos result ignored! Expected hook result to resolve to an object with an ‘_id’ property, but got an object without the ‘_id’ property

But I don’t have any hook for that collection, I cleared my data and the issue remained. It’s a repeater connected to a dataset, without any code in the page or hooks. Used to work before, but not anymore.

data.js is totally empty

You have 2 different kinds of errors:

  1. It seems that you assign 2 different data arrays to the same repeater (that’s why you have the same _id twice).

  2. Are you sure you have no hook in the backend/data.js ?
