Bug introduced by
Are you sure the assignment to $js is correct as $validator->clientValida...$this->form->getView()) targeting yii\validators\Validator...ientValidateAttribute() seems to always return null.

This check looks for function or method calls that always return null and whose return value is assigned to a variable.

class A
{
    function getObject()
    {
        return null;
    }

}

$a = new A();
$object = $a->getObject();

The method getObject() can return nothing but null, so it makes no sense to assign that value to a variable.

The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes.
