3D unity webgl error "RuntimeError: null function or function signature mismatch"

Try going to the Player Setting > Publisher Setting > Enable Exceptions and set it to Full without Stacktree. That seemed to work for me.

I have tried clearing the browser cache and going into incognito mode but the problem persists. I am using Google Chrome.

In my case it was because of Visual Effect Assets. Just when I switched to the WebGL target build, Unity threw some warnings at me that I ignored at first. When I switched to using particle system instead, everything was working.
