$key of type integer|true is incompatible with the type Doctrine\Common\Collections\TKey|null expected by parameter $offset of Doctrine\Common\Collections\ArrayCollection::offsetSet().

The expression return $it->key() also could return the type string which is incompatible with the documented return type boolean|integer.
