Re: GoogleBot is using the wrong permutation?

Ok, Still googlebot comes a long and after I deployed a new version I always get google bot exceptions.

I checked the permutation, and that often seem to be ok (not always).
That is: the one I receive as http header is the same as the one that I send a long to the backend when an exception occurs.

The error I get:
---

(TypeError) : Cannot call method 'Kg' of null 

at Unknown.vSb(https://www.leuker.nl/app/aangifte/start/)

Any idea ?
I think it might come with the JS engine that googlebot uses. For example: I don't support IE9, as I use JS features that aren't supported by IE9 that result in similar errors. 
But how to work around this? It's hard to see the exact error that occurs.

Have you tried "deobfuscating" those values (Kg and vSb) using the symbolMaps? That could possibly help understand what happens.
