Hello.
I am importing an excel to my db, and it shows me this error:

ErrorException
Undefined offset: 1

this is my model:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Cartera extends Model
{
    use HasFactory;

    protected $table = 'cartera';
    protected $primaryKey = 'codfactu';
    public $timestamps = false;

    protected $guarded = [];

}

and this is mi import file "controller"

<?php

namespace App\Imports;

use App\Models\Cartera;
use Maatwebsite\Excel\Concerns\ToModel;

class CarteraImport implements ToModel
{
    /**
    * @param array $row
    *
    * @return \Illuminate\Database\Eloquent\Model|null
    */
    public function model(array $row)
    {
        
        return new Cartera([
            'numfactura'    => $row[1],
            'codcli'        => $row[2],
            'fecha_inicial' => $row[3],
            'fecha_final'   => $row[4],
            'plazo'         => $row[5],
            'valor_inicial' => $row[6],
            'valor_saldo'   => $row[7],
            'edad_factura'  => $row[8],
            'categoria'     => $row[9],
            'tipo'          => $row[10],
        ]);
    }
}

this is my controller:

public function importarCartera(Request $request){

        Cartera::truncate();

        $file = $request->file('file');
        Excel::import(new CarteraImport, $file);

        return back();
    }

and this is my file.csv :

"19035";"1672";"634";"21/11/2019";"20/01/2020";"60";"-12524";"-12524";"424";"MAYOR A 150";"DV"
"19036";"1673";"634";"21/11/2019";"20/01/2020";"60";"-53169";"-53169";"424";"MAYOR A 150";"DV"
"19037";"1";"1399";"28/02/2018";"28/02/2018";"0";"1656284";"133984";"1055";"MAYOR A 150";"SI"

when I made a dd($row) this show me:

array:1 [▼
  0 => "19035;"1672";"634";"21/11/2019";"20/01/2020";"60";"-12524";"-12524";"424";"MAYOR A 150";"DV""
]

when I made a dump($row);

ErrorException
Undefined offset: 1

What I can be doing wrong?
