Koala::Facebook::ClientError Exception: type: GraphMethodException, code: 100, message: Unsupported get request

Question

I did research on this issue, however, nothing worked for me.

I am using Facebook Realtime subscription and graph API to track my facebook page (using page token).

When a user posts a photo/video I am getting following data pushed by fb to my server:

{"field"=>"feed",
 "value"=>
  {"item"=>"photo",
   "verb"=>"add",
   "photo_id"=>302522856593533,
   "post_id"=>"824413870916335_302522856593533",
   "sender_id"=>100005074631221}}

When I use post_id (824413870916335_302522856593533) to make call to graph API for fetching details of the post, I am encountering following error:

*** Koala::Facebook::ClientError Exception: type: GraphMethodException, code: 100, message: Unsupported get request. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api [HTTP 400]

However, if user posts without photo/video, I am able to get post details successfully. In case, admin posts photo/video, I am able to get details of that post too.

I am sure about the correctness of page token and code. I think, there must be something related to settings.

Answer 1

I have multiple pages to fetch. Tested with both of these methods Koala wiki provides

@graph = Koala::Facebook::GraphAPI.new # pre 1.2beta
@graph = Koala::Facebook::API.new # 1.2beta and beyond

Some pages have ids and some have not in their uris so in a page like this:

https://www.facebook.com/pages/Istanbul-Kuafor/241559912664906

 fc.get_object("Istanbul-Kuafor")

gives me the error message you mentioned so I use

fc.get_object("241559912664906")

if page doesn't have an id(some pages don't, somehow), I use the page name and it works this time.
