WebGL Crash / wr.requestInstances[request] is undefined

Unity Engine
1

New crash bug (sorry Marco - you probably hate me by now!), switched the compile target from “.NET 2.0” to “.NET 2.0 Subset”, and now have this crash bug showing up.

(incidentally, switching subsets did however fix the first issue with serialisation…)

At least you are making progress!

do you consistently get this error?

do you have exceptions enabled ?

3

Yes and yes to both - it’s 100% repro-able on the current build. I’m happy to zip up the folder if you want.

4

please do, this does look very much like a bug in our webgl platform layer.

5

Will do - I can’t give you the whole project unfortunately (it’s like 67GB now), but hopefully the debug build is useful.
