The method getRequest() does not exist on Backpack\CRUD\app\Library\CrudPanel\CrudPanelFacade. Since you implemented __callStatic, consider adding a @method annotation.

            $data = $this->data;
            $data[$attribute] = array_diff($value, $filesDeleted);

            $this->validateArrayData($attribute, $fail, $data);

            $this->validateItems($attribute, $value, $fail);

            return;
        }

        $this->validateArrayData($attribute, $fail);

        $this->validateItems($attribute, $value, $fail);
    }
