Error uploading file on Chrome OS

I got this error trying to upload a file on Chrome OS Version 62.0.3202.97 (Official Build) (32-bit):

Uncaught TypeError: Cannot read property 'webkitGetAsEntry' of null
Line: 87042,col: 21

Hi @stuartpb , by 'upload' do you mean drag & drop to display a file ? Is this for the online version or self hosted ?

Drag & drop or clicking the button to browse. This is for the online version at https://openjscad.org/.

Chrome, at least on ChromOS, puts null's in the DataTransferItem array. I'm not sure why, but this fixes it:
