“未捕获（承诺）未定义”在Facebook Graph API查询中使用with = location时出错 [英] "Uncaught (in promise) undefined" error when using with=location in Facebook Graph API query

问题描述

我目前正在使用Facebook Graph API开发Web应用程序。

我目前的目标是仅检索附有位置的帖子。

在检索有和没有位置的帖子已经正常工作时，我无法仅检索位置信息。

查询检索两种类型，如下所示：'/ me / feed？fields = id，name，message，picture，place，with_tags& limit = 100& with = location' p>

只能检索位置的帖子的查询如下所示： / me / feed？fields = id，name，message，picture，place，with_tags& ; limit = 100& with = location

我遇到的问题是使用参数& with = location 在我的代码的这一部分，我收到错误未保留（承诺）未定义

  if（response.paging&& response.paging.next）{
 recursiveAPICall（response.paging.next）; 
} else {
 resolve（postsArr）; 
} 
} else {
 //错误消息来自这里
 reject（）; 
} 
  

日志显示以下内容：

有没有人有可能的解决方案？

有关代码如何看到的详细信息，请参阅我的以前的问题。

解决方案

错误告诉你有一个错误，但你没有抓住它。这是你如何捕捉到的：

  getAllPosts（）然后（response => {
 console.log （响应）; 
}）。catch（e => {
 console.log（e）; 
}）; 
  

你也可以把一个 console.log（reponse）在你的API回调函数的开头，绝对有一个来自Graph API的错误消息。

I am currently developing a web application with the Facebook Graph API.

My current goal is to retrieve only posts which have a location attached.

While retrieving posts with and without location is already working, I am not able to retrieve only posts with location.

The query which retrieves both types looks like this: '/me/feed?fields=id,name,message,picture,place,with_tags&limit=100&with=location'

The query which should retrieve only posts with location looks like this: /me/feed?fields=id,name,message,picture,place,with_tags&limit=100&with=location

The problem I have is that with the parameter &with=location I get an error Uncaught (in promise) undefined at this part of my code:

if (response.paging && response.paging.next) {
    recursiveAPICall(response.paging.next);
  } else {
    resolve(postsArr);
  }
} else {
  // Error message comes from here
  reject();
}

Log shows the following:

DEBUG: -------------------------------
DEBUG: Ember             : 2.4.5
DEBUG: Ember Data        : 2.5.3
DEBUG: jQuery            : 2.2.4
DEBUG: Ember Simple Auth : 1.1.0
DEBUG: -------------------------------
Object {error: Object}
  error: Objectcode: 
    code: 1
    1fbtrace_id: "H5cXMe7TJIn"
    message: "An unknown error has occurred."
    type: "OAuthException"
    __proto__: Object
  __proto__: Object
Uncaught (in promise) undefined

Does anyone have a possible solution for this?

For further information how the code looks like see my previous question.

解决方案

The error tells you that there is an error but you don´t catch it. This is how you can catch it:

getAllPosts().then(response => {
    console.log(response);
}).catch(e => {
    console.log(e);
});

You can also just put a console.log(reponse) at the beginning of your API callback function, there is definitely an error message from the Graph API in it.
