Godot WebGL export doesn't work on Safari

[dragos-margu]

Godot version:
3.2.1.stable

OS/device including version:
macOS Catalina 10.15.4 / MacBookPro11,1
Safari version: 13.1 (15609.1.20.111.8)
Although this problem happens on the latest version of Safari, I remember that it happened on earlier versions of Safari too.

Issue description:
I quickly exported this project to WebGL and uploaded it to itch.io:
https://stone-age-jazz.itch.io/godot-weggl-test
PASSWORD: godot

The project is barebones, standard configuration, nothing has been changed.
The game does not work when running the game from Safari.
The game works when running on Firefox.

The particular error message that I get when trying to run the project in Safari is:
call_indirect to a null table entry (evaluating 'Module["asm"]["Gi"].apply(null,arguments)')

On Safari - desktop:

On Firefox - desktop:

On Chrome - desktop:

On Edge - desktop:

On Opera - desktop:

Steps to reproduce:
On macOS, run the game in Safari. It will NOT work.
On macOS, run the game in Firefox. It will work.
On macOS, run the game in Chrome. It will work.
On macOS, run the game in Edge. It will work.
On macOS, run the game in Opera. It will work.

Minimal reproduction project:
Apocalypse Now.zip

Device, version...? Is this Safari 2.0 on an iPod Touch?

I have updated the issue with all the required information, according to the template.

I think this is a duplicate of #26554.

@Calinou

According to the author of this issue #26554 his problem is with iOS Safari:
"I noticed with GLES2 that html5 exporting is working with Desktop Safari and probably Edge. But I haven't been able to get a project to work with iOS Safari."

The problem that I described is happening on laptop/desktop - macOS.
I will post screenshots for more clarity.

[Calinou]

@drmar Nevermind, I read the issue wrong.

[dragos-margu]

I made tests will all major browsers: Safari, Firefox, Chrome, Edge and Opera and posted screenshots as proof.
The only browser that doesn't work is Safari.
I hope this helps with the debug.

Project uploaded it to itch.io fails in Safari with following error, but the same project exported with 3.2.1.stable locally works:

@bruvzg

How did you check locally? I want to try it myself too.

[bruvzg]

There's "Run in browser" button in the editor (HTML5 export should be configured). It will export project and start local web server and open in default browser (you can copy URL and open it in any browser too, server will be active until stopped by the same button).

[dragos-margu]

@bruvzg

I found out in the meantime how to use Python for a quick local server: python -m http.server (http://localhost:8000)

I can also confirm that locally the exported project has no problem in Safari.

Also, if it helps with the debug, a while back I released my first game ever and it was made with Godot 3.1.2.stable
I posted the game on kongregate.com, among other places.
Here is the link:
https://www.kongregate.com/games/Stone_Age_Jazz/arza-adrenaline-rush-zombie-assault?acomplete=arza

Again, in Firefox, Edge, Chrome and Opera it works perfectly.
In Safari, it doesn't work at all. The error message is: abort(114). Build with -s ASSERTIONS=1 for more info.

I just encountered the same problem with my project (https://shanzhai.itch.io/lonely-year).

I tracked the source down, however: It's an issue on itch.io's side. I hosted the exact same project on github pages (herrnett.github.io/Lonely-Year) and it runs without any problems.
