Error when running HTML5 build

Hi,

I’m trying to package my UE4 project for HTML5 and when I run it on Firefox nightly I run into this error

A few pointer on my project

  • Built UE4 from source through github
  • I looked through all solutions listed [on this thread][2]
  • There are no problems with the emscripten and the way I built UE4. Everything else works perfectly
  • I ran the project through within the editor window and through RunMacHTML5LaunchHelper.command but run into the same error output

Any idea on what this error means and what could possibly be going wrong?

Ah ! I just posted asking about the same thing …
