JS error occurred in main process

[tiffting]

I dragged some OTF files into the fontplop window, but I'm not sure what is causing this error:

@tiffting Would you be willing to send the files you were attempting to convert to me@briangonzalez.org? I'll dig in and see what's going on.

Hi Brian,
This is an awesome project...

I'm having the same error as @tiffting with many typefaces from different origins.

An example, from a free + open source typeface:
Inter-UI-BlackItalic.otf.zip
