Closed Issue: Could not deserialize data returned from server [17036]

If you should happen to see this error when calling Users.GetInfo() it's because facebook changed something in the way their hs_info is passed down and the C# API is not expecting nullable values.

Here is the fix:

recompile the binaries from source with the following members and their referencing properties set to set to int?

These are members of > Facebook.Schema.hs_info

private int? grad_yearField;
private int? hs1_idField;
private int? hs2_idField;

If you don't have the capability or need to get your site running ASAP.. i've attached the binaries with this change already compiled in.

When authenticating an application, you will received this error.

WORKAROUND:
Turn off the new dialog in your application settings in Facebook (Developer App -> Your App -> Settings -> Migrations -> "New Data Permissions" -> Disabled

NOTE the WORKAROUND WILL STOP WORKING JUNE 1, 2010.. Code needs to be fixed before then.

Can anyone suggest how will I get the access_token?

I tried following this tutorial but I can't find the property called Secret in the facebook secret (facebookService1.Secret)
I use the facebook SDK V3.0 from page http://facebooktoolkit.codeplex.com/
but it seems to work by only using the ApplicationKey :)
Is this video for an older version of the SDK?

Commented Issue: "Incorrect Signature" error when using Stream.Publish() [15391]

dketan — Wed, 24 Aug 2011 15:00:16 GMT

I'm having a very hard time getting Stream.Publish() to work. I keep getting the "incorrect signature" error. This is a Desktop app, not Iframe or FBML. Here's the code I'm using (borrowed from someone else's example of how to make this work):

/////////////////////////////////////

attachment.caption = "www.icanhascheezburger.com";
attachment.name = "I am bursting with joy";
attachment.href = "http://icanhascheezburger.com/2009/04/22/funny-pictures-bursting-with-joy/";
attachment.description = "a funny looking cat";
attachment.media = new List<attachment_media>(){new attachment_media_image()
{
src = "http://icanhascheezburger.files.wordpress.com/2009/03/funny-pictures-your-cat-is-bursting-with-joy1.jpg",
href = "http://icanhascheezburger.com/2009/04/22/funny-pictures-bursting-with-joy/"
}};
string targetID = "100000xxxxxxxxx"; // the FB user who should receive the message
FBSession.FacebookAPI.Stream.Publish("This is a test message", attachment, null, targetID, Convert.ToInt64(FBSession.Uid));
//////////////////////////////////////////////////////

Stack trace is as follows:

Commented Issue: error-"The user hasn't authorized the application to perform this action" while posting on page [19509]

nouka — Sun, 29 May 2011 19:39:46 GMT

Hi All,

Using facebooktoolkit i am able to post on the user's wall. But i am not able to post on the page which is administered by that user.

My code is as below-
Facebook.Session.ConnectSession connectsession = new Facebook.Session.ConnectSession(APIKey, AppSecret);
Facebook.Rest.Api api = new Facebook.Rest.Api(connectsession);

api.Session.SessionKey = Auth_token;
api.Session.UserId = UserId;

Facebook.Rest.attachment_media_image myimage = new Facebook.Rest.attachment_media_image();
//href is the link for the image if you click on it
myimage.href = "http://testpage.com";
myimage.src = "http://testpage.com/image.png";
List<Facebook.Rest.attachment_media> mymedia = new List<Facebook.Rest.attachment_media>();
mymedia.Add(myimage);

Facebook.Rest.attachment myattachment = new Facebook.Rest.attachment();

//name is bold heading for entry, to right of image
myattachment.name = "Title of your post by testpage.com";
//href is the link target for the 'name'
myattachment.href = "http://testpage.com";

//caption is the long article text below the name
myattachment.caption = "Here is the main message for the wall/stream post";

//description appears under image
myattachment.description = "Something to describe the image";

myattachment.media = mymedia;

IList<Facebook.Schema.action_link> myactionlinks = new List<Facebook.Schema.action_link>();
Facebook.Schema.action_link myactionlink = new Facebook.Schema.action_link();
myactionlink.href = "http://testpage.com";
myactionlink.text = "Description for hyperlink";
myactionlinks.Add(myactionlink);

//my page
api.Stream.Publish("", myattachment, myactionlinks, "", UserId); //throws error

I have generated the access token for user(with manage_pages,offline_access,publish_stream extended permissions) and based on that access token, i am making the accounts connection (https://graph.facebook.com/me/accounts?access_token=<user_access_token>) to get the access token for the user administered page on facebook. this call successfully returns me the access token for that page.
Now i am using the same code and the access token returned from accounts connection to post the message on that page's wall.
But api.stream.publish call throws error - "The user hasn't authorized the application to perform this action"
I need to get this error resolved as soon as possible for my client, So can anyone please help me out?

Thanks
Alpesh

The Facebook Developer Toolkit has officially been discontinued. I would recommend switching to the Facebook C# SDK.
