Fields of relation populated via em.populate are not included in serialization

Hmm, I thought this was the correct behaviour, but apparently it should work this way, there is some issue with the serialization. I'll try to look into this later today, one workaround I can give you is the explicit serialization. https://mikro-orm.io/docs/serializing#explicit-serialization The other is using const users = await orm.em.find(User, {}, {
populate: ['shop.orders'],
populateWhere: {
shop: {
orders: {
category: 'A',
},
},
},
populateOrderBy: {
shop: {
orders: {
time: QueryOrder.DESC,
},
},
},
}); |

Yes, I'd say this should be the preferred way, but sometimes what you did might be a good way to split the query, since with large amounts of entities, the joined strategy might get slow on hydration. You could still use select-in strategy for such case, but if you would want to mix those (e.g. first query to select just the root entity, and second query with joins orders from shops), you would need to go with that approach. I'd still like to understand what is happening here, since the populate hint on the user entity is stored correctly even with your approach, its likely about the child entities (propagation of the hint) that is not working correctly. But it might be a limitation/wontfix, the serialization can be quite fragile because people like to mix all the approaches (combined with |

Describe the bug
I want to ultimately use
em.populateto populate the collection for each of the objects retrieved viaem.findin order to have filtered and ordered collection data. While I am able to achieve it and manipulate them within the cycle, the fields of the collections are not serialized if I try to use thewrap(...).toObject().Reproduction
