无法读取未定义的JSON Response Symfony的属性fiscalName

Question

当您尝试将变量作为索引而不是完整类型传递时，它会生成失败：

new:1668 Uncaught TypeError: Cannot read property 'fiscalName' of undefined at Object.success (new:1668) at i (jquery.min.js:2) at Object.fireWith [as resolveWith] (jquery.min.js:2) at A (jquery.min.js:4) at XMLHttpRequest.<anonymous> (jquery.min.js:4)

它表示特征“财政名称”不存在但存在。是在列表中显示“fiscalName”的值，但它不运行以下代码：

for (var i = 0; i <= parsed.length; i++) {
    $("#match").append('<li id=' + i + '>' + parsed[i].fiscalName + '</li>');
}

我的控制器

public function clientAction(Request $request) {
    $code = $request->get('data');
    $encoders = [
        new XmlEncoder(),
        new JsonEncoder()
    ];
    $normalizers = [new ObjectNormalizer()];
    $em = $this
        ->getDoctrine()
        ->getManager()
        ->getRepository('SharkBaseBundle:Person');
    $client = $em->findByFiscalName($code);
    $serializer = new Serializer($normalizers, $encoders);
    $json = $serializer->serialize($client, 'json');

    return new JsonResponse(['data' => $json]);
}
