«Неопределенное свойство: stdClass :: $ name» не может прочитать данные из ng-модели ?? (Angularjs, PHP, MySQL)

Question

Я пытаюсь добавить некоторые данные в свою базу данных через форму. Но я получаю ошибки в консоли

"Undefined property: stdClass::$name in ..." (эта ошибка в create.php строке 6.) Я получаю эту ошибку для каждой строки, с которой пытаюсь прочитать данные (рисунок ниже). Я не могу понять, почему это не работает.

Сообщения об ошибках консоли

create.php

<?php
include '../src/config/db2.php';

$data = json_decode(file_get_contents("php://input"));

$advertiser_name = $data->name;

$advertiser_phone = $data->phone;
$advertiser_address = $data->address;
$advertiser_postcode = $data->postcode;
$advertiser_location = $data->location;
$advertiser_billAddress = $data->billAddress;
$advertiser_billPostcode = $data->billPostcode;
$advertiser_billLocation = $data->billLocation;

$sql = "INSERT INTO `tbl_advertisers` (
  `advertiser_name`,
