错误：$ resource：badcfg无法使用ngResource更新用户数据

Question

我正在尝试编辑资源并在我的编辑表单上显示用户数据。除了更新之外，我的所有其他CRUD操作都在工作。有人可以帮助我理解并纠正这个错误：

错误：$ resource：badcfg响应与配置的参数

不匹配

以下是代码：

form.adults.html

<td><a ui-sref="form.adults-edit()"><button class="btn btn-primary btn-sm">Edit</button></a></td>

app.js

var app = angular.module("LunchApp", ["ngVidBg", "ngAnimate","ui.router",'ngResource']);
app.config(function($stateProvider,$urlRouterProvider) {

  $stateProvider

 .state('form.adults-edit', {
    url: '/adults/{{adult._id}}/edit',
    controller: "EditAdultController",
    templateUrl: "views/a-edit.html"
  })

 $urlRouterProvider.otherwise('login');
  });

services.js

app.service("AdultService",['$resource', function($resource){
    return $resource('/api/adults/:id', {id: '@_id'}, {
        update : {
            method: 'PUT'
        }
    });
}]);

controllers.js

app.controller("EditAdultController", function($scope, $location, $stateParams, AdultService){
  AdultService.get({id: $stateParams.id},function(adult){
    $scope.adult = adult;
    console.log(adult);
  }, function(err){
    $state.go('form.adultsInHousehold1');
  });
  $scope.editAdult = function(adult){
    console.log("This is working!");
    $scope.adult.$update(function(){
       $state.go('form.adultsInHousehold1');
    });
  };
});
