I tried to use for the “find” an controller like this:
module.exports = createCoreController('api::favorite.favorite', ({ strapi }) => ({ async find(ctx) { ctx.query = { ...ctx.query, 'populate':'*', 'Owner.id':ctx.state.user.id} return await super.find(ctx); } }));
But I get still all documents and the field with the relation is never visible by the API: All the other relations work as aspected.
