Facebook open graph GraphMethodException error code 100

Question

I'm trying to work my way through the Facebook tutorial publish and open graph story for iOS, https://developers.facebook.com/docs/tutorials/ios-sdk-tutorial/publish-open-graph-story/

Step 3 is failing for me. When I use the graph API explorer I get the error

{
  "error": {
    "message": "Unsupported post request.", 
    "type": "GraphMethodException", 
    "code": 100
  }
}

I've looked through a bunch of answers on stack overflow relating to this error but none seem to be my problem. I have selected get access token and have publish permissions. The page is not alcohol related and the user page I'm using is not age restricted.

I have selected my application from the top of the page. I have selected post and then entered my story object in the space provided me/gopiratestd:boss

then I add a new field and use the key beat on the left and then the following url on the right. https://hidden-castle-7245.herokuapp.com/opengraphobject.php?fb:app_id=554329451276476&og:type=gopiratestd:boss&og:title= beataboss&og:description=%22Beat%22&og:image=http://images.all-free-download.com/images/graphicmedium/beautiful_cat_picture_6_168770.jpg&body=Beat

Then when I hit submit it returns that error.

Is there anything obvious I'm doing wrong here?

When I use that link in the object debugger it doesn't return any errors.

Answer 1

Error 100 means that there is a plain syntax error in the URL you are posting to.

I suspect you have a custom graph url set which doesn't match your action - see http://developers.facebook.com/docs/opengraph/creating-action-types :

Graph API URL This customizes the exact endpoint used when publishing actions, which by default for custom action types is /me/{app-namespace}:{action-type-name}.

Answer 2

Your action is beat, your object type is boss so it should be

me/gopiratestd:beat

and

boss=https://hidden-castle-7245.herokuapp.com/opengraphobject.php?fb:app_id=554329451276476&og:type=gopiratestd:boss&og:title= beataboss&og:description=%22Beat%22&og:image=http://images.all-free-download.com/images/graphicmedium/beautiful_cat_picture_6_168770.jpg&body=Beat
