If someone knows how to solve this problem, I will be very grateful

this is my code from import file

use Importable;
public function model(array $row)
{
    HeadingRowFormatter::default('none');
    return new ImportPassportCounter([
        'OS_RAH' => $row[0],
        'N_MARK' => $row[1],
        'ZAV_NOMER' => $row[2],
        'DIAM' => $row[3],
        'N_MISC' => $row[4],
        'DATA_VST' => $row[5],
        'DATA_POV' => $row[6],
        'DATA_NAST_POV' => $row[7],
        'KIL_MISIAC' => $row[8],
        'POP_POK' => $row[9],
        'OST_POK' => $row[10],
        'TIP' => $row[11],
        'KON_POK' => $row[12],
        'DATA_KON_POK' => $row[13],
        'DATA_N_PLOMB' => $row[14],
        'N_PLOMB' => $row[15],
    ]);
}

public function chunkSize(): int
{
    return 1000;
}

this is my code im Model file

class ImportPassportCounter extends Model
{
    use Notifiable;
    protected $table = 'import_passport_counters';
    protected $fillable = [
        'OS_RAH',
        'N_MARK',
        'ZAV_NOMER',
        'DIAM',
        'N_MISK',
        'DATA_VST',
        'DATA_POV',
        'DATA_NAST_POV',
        'KIL_MISIAC',
        'POP_POK',
        'OST_POK',
        'TIP',
        'KON_POK',
        'DATA_KON_POK',
        'DATA_N_PLOMB',
        'N_PLOMB',
    ];
}

this is my migration file

Schema::create('import_passport_counters', function (Blueprint $table) {
        $table->id();
        $table->text('OS_RAH')->nullable();
        $table->text('N_MARK')->nullable();
        $table->text('ZAV_NOMER')->nullable();
        $table->text('DIAM')->nullable();
        $table->text('N_MISK')->nullable();
        $table->text('DATA_VST')->nullable();
        $table->text('DATA_POV')->nullable();
        $table->text('DATA_NAST_POV')->nullable();
        $table->text('KIL_MISIAC')->nullable();
        $table->text('POP_POK')->nullable();
        $table->text('OST_POK')->nullable();
        $table->text('TIP')->nullable();
        $table->text('KON_POK')->nullable();
        $table->text('DATA_KON_POK')->nullable();
        $table->text('DATA_N_PLOMB')->nullable();
        $table->text('N_PLOMB')->nullable();
        $table->timestamps();
    });

this is my code in Controller

$import = Excel::import(new PassportCounterImport, $request->file('file'));
    if ($import)
    {
        $result['success'] = true;
        $result['message'] = 'Success';
        return response()->json($result, 200);
    }
