Error loading compiled project with emscripten 1.38.31

[ejvc]

I´m compiling a Qt 5.13 project using emscripten 1.38.31...

It compiles, but when I load it, I get this error:

                  TypeError: Body has already been consumed.

Can someone explain me why I'm getting this error please? 

[ejvc]

I solved it, it wasn't a compiler issue... 

After a long debugging time... I found that I must activate SharedMemory in Firefox ( about:config )

It worked for me, I hope this could help someone else
