Fatal error: Uncaught OAuthException: (#803) Some of the aliases you requested do not exist

Question

Fatal error: Uncaught OAuthException: (#803) Some of the aliases you requested do not exist: 0_309479102458745 thrown in /base_facebook.php on line 1039

My app was working fine and then suddenly many users are gettings this error (with the exception of 0_309479102458745 varying somewhat).

I changed it to treat them as varchar and followed all the suggestions listed here Facebook PHP throwing exception "(#803) Some of the aliases you requested do not exist".

here is the code causing it: $result = $facebook->api('/me/feed/', array('access_token' => $facebook->access_token,'limit'=>50)); //get posts foreach($result['data'] as $posts)

I'm not sure exactly where I should begin troubleshooting this since it started out of nowhere.

I appreciate your help!

Solution

0_309479102458745 won't work because 0 isn't a valid user ID.

That format of ID is a User or Page ID followed by the post ID; you should never be seeing 0_{post ID} coming back from the feed:

• if you are it could be a bug in the API - you can file it here: https://developers.facebook.com/bug
• if you're manually constructing that value, you may be doing so incorrectly.

@RobertBlair Have you finally find where does it come from? I meet exactly the same problem. Some times, when parsing the home news feed of a user, I get twice the same post, with one that has a 0_<post-id> id and the other one that has the good id syntax, ie <user-id>_<post-id>.
