JavaScript execution returned a result of an unsupported type

I got this error when loading flutter HTML editor.

I forked this library and have made some pretty massive changes to it, you can find it here. I've fixed this issue (and many others) in that library.

I would have preferred to create PRs but it seems this library is lacking maintenance so I took it upon myself.
