Failed to initialize basis worker: Error: WebAssembly.Module doesnt parse at byte 4572: invalid opcode 192, in function at index 73

Help & Support
1

Hello all,

so this game I’m working on gets stuck on the loading screen when running it on older devices (issue originally found on a ipad mini 5).

When I check the console logs, there is some error logs that I think could be causing it to get stuck… Failed to initialize basis worker: Error: WebAssembly.Module doesnt parse at byte 4572: invalid opcode 192, in function at index 73

If anyone has any ideas on what this error could be caused by, or if they are able to re-produce it in other projects that would be great.

Thank you very much

Thanks, I will take a look. I guess I would just re-import basis in the editor to update to the latest version of basis containing the fix?

Yep, that worked in the past.

Ok first I will try updating basis to the latest version and see if that fixes it. Thanks

I re-imported basis, but seems like it still doesnt work.

I am also getting this error aswell as the other one I posted (although both seem simular and maybe link to the same issue)…

Could you please try and use files from here, as these are definitely up to date:

If this issue persists, we might have a new problem.

Unfortunately it seems the error still occurs with the latest files.

I tested on this device through browserstack…
iPad Mini 2019 v12.2

Apparently it also got stuck on this device aswell (probably the same issue)
iPad Mini 5 iOS 17.4.1

Maybe if I try reproduce on any other project with basis? I could setup as new small project and import basis? what do you think? if that works then it must be some issue with the project on my end

A simple repro project is always a good idea, even for your own self. Try a blank project with a sample texture and compress it with Basis.

I tried this example: Basis Example - PLAYCANVAS

it seems to load fine. So something must be wrong with the code on my end then I’m assuming (which I am investigating).

It’s Safari issue, not your issue … but it seems they handled the updated wasm fine (without anybody adding any fixes to it).
The issue we had was to occasionally (maybe 1:3) get the issue, not 100% … are you getting yours 100% of time? On all basis textures, or just some of them? We only had it on some I think.

Ok thanks. Yes so far its happened everytime. I can try loading a different scene to check if it happens on all the basis textures or just some

16

I tried using no basis textures in a scene (just a blank scene more or less). However, still got the issue, but I have some textures set to preload that use basis so I guess maybe that’s why

However, ive noticed that im getting this error on chrome…

very odd. Unless the device i’m testing on is too old haha

@mvaligursky hmm, the link above gives me another error (Win11, Chrome):

Doesn’t happen in stable Chrome. Happens in Version 128.0.6613.7 (Official Build) beta (64-bit)
