Question

I am getting bellow error recently my currently using app. when try to insert record using eloquent. This code was perfectly working in past few months. Now it just throwing the error after '1303' records inserted.

Translate from: English SQLSTATE [23000]: Integrity constraint violation: 1062 Duplicate field '1304' for the 'PRIMARY' key (SQL: insert into orderrequest

    $today = date("Y-m-d H:i:s");
    $order = OrderModel::find($id);
    $kot = new OrderrequestModel;
    $kot->orid = $id;
    $kot->location = $order->location;
    $kot->provider = "kitchen";

    $orderitems =OrderitemModel::where('orid', '=', $id)->get();
    $total = 0;


    foreach ($orderitems as $orderitem) {
        //$total = $total+($orderitem->price * $orderitem->qty);
        if($orderitem->provider=="kitchen"){
    $kot->token .= '<tr>
            <td align="left">'.$orderitem->fiid.'</td>
            <td align="left">'.$orderitem->item.'</td>
            <td align="center">'.$orderitem->provider.'</td>
            <td align="center">'.$orderitem->qty.'</td>

          </tr>';
          $orderitem->isreq = "k";
          $orderitem->save();
        }
    }
    $kot->token .= '</table>';
    $kot->type = "full";
    $kot->save();
