ParseFacebookUtils.LogInAsync gives an error on WebPlayer only
I am using the Parse Unity SDK along with the Facebook Unity SDK in my game so users can log in with their Facebook account.
It's working well on mobiles (Android and iOS), and in the editor.
In Facebook Canvas (WebPlayer), on my machine (Mac Mini), with my main session (Administrator), with every browsers (Chrome, Safari, Firefox), I get an error upon calling this code :
Debug.Log("ABOUT TO LOGIN");
ParseFacebookUtils.LogInAsync( FB.UserId,FB.AccessToken,
FB.AccessTokenExpiresAt).ContinueWith(x =>
{
Debug.Log("IN TASK");
if(x.IsFaulted || x.IsCanceled)
{
Debug.LogError("[FacebookManager] Error LogInAsync");
Debug.Log(x.Exception);
}
else
{
// Connection successful
// ...
}
}
// CODE CONTINUES...
The output is as follows :
ABOUT TO LOGIN

This error doesn't appear on other sessions on my machine, and it doesn't appear on my teammates' machines either.
Here is what I tried so far (not necessarily in that order) :
- Cleared browsers caches
- Tried in private navigation mode
- Going to unity3d.com/webplayer/setup to delete all cached files
- Going to unity3d.com/webplayer/setup to disable caching of files
- Uninstalling and fresh install of the Unity Web Player (downloaded from Chrome)
- Uninstalling and fresh install of the Unity Web Player (downloaded from Firefox)
- Deleted all WebPlayerPrefs on my machine
- Changed permissions of PlayerPrefs folder and files to rw for everyone
- Uninstalling Unity Web Player, Copy of the Unity Web Player files from the mac where the error doesn't appear to install manually
- Including PlayerPrefs.DeleteAll()` in my code before LogInAsync
Additionaly, there are numerous times where the game doesn't even load (blank canvas instead of Game Logo + loading bar). Blank web player also happens sometimes when going to unity3d.com/webplayer/setup.
I am fairly certain that the problem comes either from a permission conflict, or a cache I don't know of.
Any idea what I can try now ?
I encountered the same issue. In my case problem was in the Web Player Development Release Channel. Try to switch from Development to Release Channel.
