when I'm trying to make sorting of client.firstname for example I have an error what should I do in this situation? Who had the same problem? It has method $this->setRelationSort($this->sort['column']); but does not work
$grid->column('client.firstname',$label)->sortable();
ErrorException In Macroable.php line 102 :
