Sometimes I got exception with the following code;

//string groupId;
//int? gameType;

SFSObject sfsObject = new SFSObject();

if (!string.IsNullOrEmpty(groupId))
       sfsObject.PutUtfString("groupId", groupId);

if (gameType.HasValue)
       sfsObject.PutInt("gameType", gameType.Value);

How can I fix it ?

Stack Trace;

Hi,
the code looks incomplete. What happens next?
I mean after those two conditions.

Is there a way in which the error can be reproduced? Does it depend on those two conditions? If so how?

Thanks

Code: Select all

//string groupId;
//int? gameType;

SFSObject sfsObject = new SFSObject();

if (!string.IsNullOrEmpty(groupId))
       sfsObject.PutUtfString("groupId", groupId);

if (gameType.HasValue)
       sfsObject.PutInt("gameType", gameType.Value);
	   
smartfox.Send(new ExtensionRequest("playGame", sfsObject, null));

I found this exception Crashlytics. I can not reproduce it.
