Bug "Null function or function signature mismatch" error when Native .a plugin used in WebGL

It says this to my WebGL game. Is there any fix to it!? please reply.
Is there any chance that this is because of lighting and baking?
I've tried building with both speed and size on code optimization. But it still shows the same.
Thanks in advance!

 

Hi, I would recommend you to try a build with enabled stacktrace, to see what functions cause your error. The provided information is not enough to find out what's wrong with your build.

 

I am facing the issue now for my 3d game build after deployment I have some seasons like the login level page and game page and I can log in and level page also working after entering the game the error will show "

 

its working properly for me when I have solved this issue by changing Player Settings > Publishing Settings > Enable Exceptions to Full Without Stacktrace.
