It seems like $filter can also be of type array; however, parameter $json of json_decode() does only seem to accept string, maybe add an additional type check?

                    $dataProvider->query->andWhere([$filterUserColumn => Yii::$app->user->getId()]);

The method getId() does not exist on null.

The expression $model->delete() of type false|integer is loosely compared to true; this is ambiguous if the integer can be 0. You might want to explicitly use !== false instead.

                        $this->_deletedModels[] = $model;
                        $countDeleted++;
