Looks like the same problem as this - commenting out those same lines resulted in data being returned:

> [@Rest API in Mautic 5 delivers empty result array but no error](https://forum.mautic.org/t/rest-api-in-mautic-5-delivers-empty-result-array-but-no-error/30596/6):

> There is a method in Entity\Lead.php that sets groups for this serializer.
