Error occurs when I run the sample project for facebook leaderboard

+1 vote

I am trying to integrate facebook leaderboard in my app following the page below.

I think I did what the page says. I registered my app and got two keys.

Then I ran the sample project with the app name and these 2 keys, and I got these 2 errors.


You are trying to load data from a www stream which had the following error when downloading.

400 Bad Request


<execute>c__Iterator1:MoveNext() (at Assets/Examples/Scripts/AppConstant.cs:103)

<WaitForRequest>c__Iterator0:MoveNext() (at Assets/Examples/Scripts/AppConstant.cs:66)


NullReferenceException: Object reference not set to an instance of an object

AppConstant.callBack (System.String response) (at Assets/Examples/Scripts/AppConstant.cs:45)

AppConstant+<execute>c__Iterator1.MoveNext () (at Assets/Examples/Scripts/AppConstant.cs:103)

AppConstant+<WaitForRequest>c__Iterator0.MoveNext () (at Assets/Examples/Scripts/AppConstant.cs:66)



Did I miss anything or do something wrong?


One more question.

What I can do is that I save scores of mine or my facebook friends into the storage of facebook,

and I can display those scores on the form that i make. (Facebook does not support any forms about this)

Is it correct?

I think you are trying to run this sample on unity3d editer. And Facebook Unity3d SDK doesn’t  support editor/desktop applications at the moment. You must run this app on For more information about Unity3D Facebook SDK visit Getting-started with Unity Facebook.
