"Uncaught (in promise) undefined" error when using with=location in Facebook Graph API query

Question

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.

Answer 1

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.

More information: https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Global_Objects/Promise/catch

Or with async/await:

//some async function try {     let response = await getAllPosts(); } catch(e) {     console.log(e); }
