WebGL NullReferenceException with no stacktrace in Performance Reports

Unity Engine
1

Hello,

I have a project running on WebGL/iOS/Android (http://nitrodrift.io) and I have noticed a NullReferenceException that happened more than a million times with no stacktrace! Some other exceptions happened but I have a stacktrace for all of these. However, I have nothing about this huge bug.

Any ideas why ? How can I manage to get a stacktrace?

Please note that this bug only happens in WebGL, nobody has had this bug on the mobile platforms and I can’t reproduce it, even in the editor.

Screenshot of my performance report page attached below.

Exception Message: NullReferenceException: A null value was found where an object instance was required.
Attached stacktrace:


Native StackTrace:```

Thank you for your help!

Hello again,

Nobody has an idea of why is this happening ? Unity’s support did not answer either…

There’s a known issue with callstacks sometimes being null/empty, which seems to affect multiple IL2CPP platforms. It might be the same problem.

Has this only occurred once?

Hello @Marco-Trivellato ,

Unfortunately no, This keeps happening and now I have a NullReferenceException that happened almost 5 million times since in the past 14 days. Is there any fix I can try ? (new build options or whatever comes to you)

Thank you for looking into this !
