Thank you for trying the script.
That script requires the --export-es6 flag to file_packager.py. This flag
was introduced in Emscripten 4.0.13 so please update the Emscripten tools if
it is not available. If you're using emsdk, it provides the way to intall
newer tools, such as "emsdk update" and "emsdk install 4.0.23" [1].
