It throws on Firefox too. But this is weird… I would have bet to have tested it about one month ago, and I don't really understand the message, given the code. (even with the debugger).

I think I found it.

The code at github-pages is outdated. The code in the repo does work. Apparently there was an error when deploying it to github-pages:
