WebGL loading error _Znwj and -1 in Unity 2020.3.1f1

Unity Engine

Hi,

I have successfully build the WebGL with compression disabled, when loading in browser by hosting in server or using local host getting errors as abort(-1) and _Znwj, what could be the solution for this, also how to allocate memory for browser.

Invoking error handler due to
abort(-1) at Error

Can you make a Development build and test again? That should give a proper callstack that does not have those cryptic “wasm-function[10789]” frames in them, but instead will have proper function names that can give a clue as to where the issue comes from.

3

Dev build also giving the same error

4

Can you post the callstack? In a Dev build there will not exist those lines like

at https://localhost:8080/Build/c8784875e9fb266c54beb524c35a1f9a.wasm:wasm-function[88053]:0x192dfc1

but there will be full function names.

5

Could you please help on this, getting this error when I takes dev build, it’s with another project

Normal build is successful but have following errors mentioned in the beginning
_Znwj and -1

Already answered to this in the other thread at Development Build fails in WebGL development :

This error is quite peculiar, these lines are saying that the functions

std::__2::basic_string<char, std::__2::char_traits, std::__2::allocator >::reserve(unsigned int)
operator new[ ](unsigned int)
operator new(unsigned int)

are missing, though these should be coming from the standard C++ library, they are not Unity provided functions.

Are you by any chance compiling any plugins in your code that are precompiled for WebGL? The fact that all of those have the parameter “unsigned int” in them suggests that maybe the version they were precompiled for is out of date. Try removing external plugins from the project if so to see if one of those would uncover the issue.

I am using DoTween, Xzimng for face tracking and Gltf - all supports WebGL, will check it
