Laravel relationship conflicts in union

The only way for now is to use from map.

public function usersAndOrganizations()
{
    $users = $this->users();

    $organizations = $this->organizations();

    $invitees = $users->union($organizations)->paginate(10);
  
    $invitees = $this->getRelatedData($invitees);

    return response()->json($invitees);
}


private function getRelatedData($invitees)
{
    $invitees->map(function($object) use($functionalAreaName) {
        if($object->type == 'business') {
            $relationName = 'businesses';
            $relationKey = 'business_id';
            $attachableType = Business::MORPHABLE_TYPE;
        }
        if($object->type == 'freelancer') {
            $relationName = 'users';
            $relationKey = 'user_id';
            $attachableType = User::MORPHABLE_TYPE;
        }
        $functionalAreas = FunctionalArea::whereHas($relationName, function($q) use ($object, $relationKey){
            $q->where($relationKey, $object->id);
        })->get([$functionalAreaName.' As name', 'id']);

        $object->functional_areas =  $functionalAreas->toArray();

    });

    return $invitees;
}

And remove with from your functions, and call this after you get the paginated result.
