I'm still seeing problems...
I use the Perl API
[Thu Jul 17 22:59:08 2008] [error] garbage after JSON object, at character offset 5 ["erver closed connection without sending any data back\\n"] at /usr/lib/perl5/site_perl/5.8.8/JSON/Any.pm line 437\n

Didn't really put too much effort into investigating as I was hoping that a very important problem such as this would have been adressed immediately..

anyway... quick investigation points toward the $facebook->friends->get_app_users(); call.

was failling like crazy today... but is kinda failing much less... but still significative.

I appologise about my post being not too technically usefull.. but its just to say that wahtever that was done.. helped towards solving the probem... but its still not completely solved.

I'm seeing this as well on FQL queries. It's intermittent, but this code:

$array = $facebook->api_client->fql_query($fql);

is sometimes returning the correct result set, but is sometimes empty. I'm not getting any errors or exceptions, just an empty result.

This is primarily the issue i've been having too. it started yesterday afternoon and got steadily more frequent during the day. If i refresh a page a couple of times the fql works fine.

I've also been finding that FBJS elements are simply not working unless I refresh the page.

These issues are being reported by my application users, but not all of them, and i've also seen them myself but there doesn't seem to be any specific pattern.

i've noticed a general deteriation in the api services over the past week, having had a night with similar problems a few days ago which seemed to be resolved soon after. I am loosing users because my app is affected while rival apps do not seem to have any problems, yet nothing in my code has changed.

here is a recent one for a simple users.getInfo call


In facebookapi_php4_restlib.php (line 1649) I entered the following two echo's

       echo "<!-- Using {$this->server_addr} //-->";
       echo "<!-- POST String = {$post_string} //-->";

and here are the results

<!__ Using http://api.facebook.com/restserver.php //__>
<!__ POST String = uids=xxxxxxxxxx&fields=last_name%2Cfirst_name%2Chometown_location%2Cbirthday&method=facebook.users.getInfo&session_key=xxxxxxxx&api_key=xxxxxxxxxx&call_id=1216374459.1503&v=1.0&sig=b34a884593076c1676fbfcf078824c92 //__>

And the return value was empty causing the following prob:

<b>WARNING</b> isterxmlexpatnonvalid_>parse(): expat: no element found [_1/0/1]<br />

I'm still seeing problems with sending LiveMessages from the API. I reported the details yesterday in Bug #2632. 
http://bugs.developers.facebook.com/sho … gi?id=2632

Here is what I reported, for those without a Bugzilla account:

While communicating with Facebook's server to send a LiveMessage from my server
via the Facebook API, I am receiving a "Connection reset by peer" error
message, as if the connection is dying.

I am using the PyFacebook library for accessing these API functions via Python.
I modified the code to add in support for the LiveMessage protocol. This has
worked with no problems up until today, which gives me some confidence that it
is a problem with Facebook and not my end.

The failure occurs only about one out of every ten times. I have only seen it
with sending a LiveMessage, but it is possible that it happens for other API
calls as well, since most of my calls are LiveMessage calls.


Here are the relevant parts of the stack trace:

<urlopen error (104, 'Connection reset by peer')>

I'm still having issues on all 3 of my apps, which worked fine before, just had this error:

I am still having major problems with API calls...they are not timing out right now, but are incredibly slow (taking over 3-5 seconds).  My app is http://apps.facebook.com/sexyvoice/

You can see the effect of it by going to http://apps.facebook.com/sexyvoice/invite.php where I  make the following call:

$rs = $facebook->api_client->fql_query("SELECT uid FROM user WHERE has_added_app=1 and uid IN (SELECT uid2 FROM friend WHERE uid1 = $user)");

Can someone please look at this issue as soon as possible.  It has cut down my traffic in half over the last day and I have no control over it.

I'm still getting this error.  Matters have not improved one bit.

I too am facing this. Its unbelievable its been going on for so long.

I've started experiencing "HTTP error code 500" too.

I'm getting a number of errors in different parts of my code, and usually its a "Cannot use string offset as an array" error.

As an example, my joyent error log says:
[Fri Jul 18 12:30:48 2008] [error] [client 204.15.23.168] PHP Fatal error:  Cannot use string offset as an array in /home/d96402f6/web/public/brainiversity/config.php on line 26

This is the code (line 26 is the second line):
   $user_details=$facebook->api_client->users_getInfo($uid, array('last_name','first_name'));
   $username=$user_details[0]['first_name'];

Like a lot of people here, I'm getting the error randomly.  My app will work, then it won't.

I am facing this problem too. Sometimes, my app is working really fine, and sometimes it just brakes. I observe that the problem is with mainly users.getInfo function

We're experiencing the same issues with API calls, WARNING isterxmlexpatnonvalid->parse(): expat: no element found [-1/0/1]

As well as others errors, not sure if they related. It would be great to get a response from FB to let us know if they are working on it. Should we attempt to retrieve the information using FQL? Please advise.

FQL queries are behaving in the same, unexpected manner.

Here is my setup:
api.facebook.com
PHP5 Legacy library

The calls that fail a lot are:
$facebook->api_client->users_getInfo($uid, array('last_name','first_name', 'current_location', 'hometown_location', 'affiliations'));
$facebook->api_client->fql_query("SELECT last_name, first_name, hometown_location, affiliations, current_location FROM user WHERE uid=$user");

Please let us know what can be done to fix this or workaround it... thanks!

We're getting problems with string offsets in arrays too. Looks like it's associated with network affiliations.

I think that error comes from facebook returning an empty array which causes the string offset error.  however this is the same issue that we're all experiencing which is that the api is returning empty results or just erroring out.

Hello all.

Our app is still seeing a lot of connection error: #<Errno::ECONNRESET: Connection reset by peer>
And I traced a few of them. They are calling various facebook APIs that have worked before, and they are working semi-consistently.

Plus, I have two apps running in two different networks. They both exhibit the same issues. So I know it is probably not my ISP.

Facebook team, what can we do to help you diagnose this problem?
thanks.

List of a few connection reset errors in the last few hours:

Where do you see those connection reset errors?  I am trying to look for logs or something like you are looking at.  is that on your server or are there facebook logs for my app somewhere that I don't know about?  thx.
