Чанк метода не существует, когда я импортирую файл Excel

Question

Я пытаюсь импортировать 100к данных в базу данных из Excel, и у меня возникают проблемы с тайм-аутом, поэтому я использовал метод chunk, но он говорит, что «метод chunk не существует». Как я могу решить эту проблему?

Excel::filter('chunk')->load($request->file('excelFile')->chunk(900, 
function ($reader) use ($electionId, &$voterCount, &$lastVoter,&$rowError) 
{
     foreach ($reader->toArray()[0] as $row) {
     $voter                  = new Voter();
     $voter->electionId      = $electionId;
     $voter->voterNumber     = $row['voter_id'];
     $voter->name            = $row['name'];
     $voter->password        = $row['password'] === 
     null || $row['password'] == '' ? rand(1,100000) : $row['password'];
     $voter->emailAddress    = $row['email'];
     $voter->mobileNumber    = $row['mobile_number'];



     }
     }));

Я загрузил детали дилера.Попробуйте это, это работает в моем случае:

public function addDealerByAdmin(Request $request_body)
{ 

    if ($request_body->hasFile('file')) {
            //if ($_FILES['file']['type'] == "text/csv" || $csv_file_type = array('text/csv')) {

            $file_array = Input::file('file');
            $file_name = $file_array->getClientOriginalName();

            //Log::info('file_type : ', ['file_type' => $_FILES['file']['tmp_name'], 'file_ext' => File::extension($file_name)]);

            if (File::extension($file_name) == 'csv') {
                // Good to go

                $csv_file_type = array('text/csv');
                $csvMimes = array('application/vnd.ms-excel');
                $filename = $_FILES["file"]["tmp_name"];
                $file_type = $_FILES['file']['type'];
                $csvFile = fopen($filename, 'r');
                //skip first line
                fgetcsv($csvFile);
                DB::beginTransaction();
                $i = 2;
                //parse data from csv file line by line
                DB::delete('DELETE FROM dealer_master');
                while (($line = fgetcsv($csvFile)) !== FALSE) {

                            $count = $count + 1;
