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

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

                $previousValue = Arr::get($this->data, '_order_'.Str::before($attribute, '.'));

The expression return parent::field($rules) returns the type Backpack\CRUD\app\Library\Validation\Rules\BackpackCustomRule which includes types incompatible with the type-hinted return Backpack\CRUD\app\Library\Validation\Rules\ValidUpload.
