The same question , I want to post a comment using the graphical API. after I tried for a while, I managed to post a comment on the wall and the wall of friends. When I try to publish a URL, I get an error:
{ "error": { "message": "An unknown error has occurred.", "type": "OAuthException" } }
But if I try to see (get) the comments at this URL, I can see them without any problems. I will be a clearing to hear the answer to this question in advance.
For testing, I used: Graph API Explorer and Facebook Debugger
