WebGL Wont Build - Crash Monitoring with UnityPerf / GamePerf

Hi All,

I'm wondering what folks are using for Crash Reporting with Unity's WebGL? We'd love to know a client is having issues before they contact us.

The only downside I see to the Unity Analytics (which seem to be working well for us by the way) is that it doesn't allow us to do any crash reporting.

I tried jumping on UnityPerf which allows pretty painless crash reporting integration... until we try to build. Using Unity 5.3.1f1 anytime we try to build our project with UnityPerf included, we get the following error in the console log (note: This happens regardless of Strip Engine Code being enabled or changing from NET 2.0 Subset to NET 2.0 ).

Including the DLL and using UnityEngine.CrashLog; in of itself doesn't seem to cause the error.

However, when we actually try to the init:

Code (CSharp):

1. CrashReporting.Init("...");

It causes the build error below.

The error message we are seeing is:

Spoiler

Code (CSharp):

Has anyone had success integrating this into WebGL with Unity 5.3.1 or is it something on my system?
It looks like exactly the solution we need, so in the offset chance it'll get fixed, I submitted a bug report #
759297

 

Accidentally posted this under my work account - posting so I can follow

 

Same problem with UnityEngine.CrashLog. Unity 5.3.3

 

Fyi

Unity team confirmed they won't be fixing the bug above and closed the ticket. You may want to open one for CrashLog
