I have a problem in ng-repeat, can help me please?

Php code

public function listar_extras() {
    $data = json_decode(file_get_contents("php://input"));

    $tamanho = $data->tamanho;
    $sPizza = $data->sPizza;
    $cont = 0;
    for ($x = 0; $x < count($sPizza); $x++) {
        $nome = $sPizza[$x]->prod_nome;
        $result = $this->pedidos_painel_model->listar_extras($tamanho, $sPizza[$x]->prod_id);
        for ($i = 0; $i < count($result); $i++) {
            if ($result[$i]->ins_nome !== null && $result[$i]->ins_nome !== '') {
                $tamanho = count($result[$i]->ins_nome);
                if ($tamanho > 38) {
                    $nome_cortado = substr(0, 36) + '...';
                } else {
                    $nome_cortado = $result[$i]->ins_nome;
                }
                $extras[$cont]['extra_id'] = $result[$i]->extra_id;
                $extras[$cont]['extra_valor'] = $result[$i]->extra_valor;
                $extras[$cont]['ins_id'] = $result[$i]->ins_id;
                $extras[$cont]['ins_nome'] = $result[$i]->ins_nome;
                $extras[$cont]['ins_nome_cortado'] = $nome_cortado;
                $extras[$cont]['prod_cl_nome'] = $result[$i]->prod_cl_nome;
                $extras[$cont]['prod_nome'] = $result[$i]->prod_nome;
                $extras[$cont]['existe'] = true;

                $cont++;
            } else {
                $extras2[$cont]['prod_nome'] = $nome;
                $extras2[$cont]['msg'] = 'Não há alterações para este sabor!';
                $extras2[$cont]['existe'] = false;
                $cont++;
            }
        }
    }

    $extras[$cont] = $extras2;
    ?><pre><?php
    print_r($extras);
    exit();


    if (count($extras) === 0) {
        $extras = 0;
    }
    echo json_encode($extras);
}

Repeat code

<section  ng-repeat="(key, value) in saboresComExtras| groupBy:'prod_nome'">
                        <div class="col-md-12 padding-zero">

Code of the Angularjs

$scope.carregarExtras = function () {
        $http.post(url_sistema + 'pedidos_painel/listar_extras', {'tamanho': $scope.tamanho, 'sPizza': $scope.sPizza}).success(function (data, status, headers, config) {
            $scope.saboresComExtras = data;
        }).error(function (data, status) { // called asynchronously if an error occurs
            console.log(data);
        });
    };

This error happens because some value is being repeated, example a name that is similar in more than one object. To solve this, just use the track by and defined by a single value, such as $index. Remembering that you can set by a field of your array as well, as long as it is unique. For example, an id.

ng-repeat="(key, value) in saboresComExtras| groupBy:'prod_nome' track by $index"
