I'm sorry to bother you again, but I got a problem when uploading from the FileChooser with metadata.
This is my code:
When I preview in NW.js or Chrome, it gives me this error:
When I export to NW.js or preview in any other browser, it just never finishes uploading.
(I know that because there is a text object that would change if it finished)
Uploading a simple string with the same settings works perfectly.
Any advice what I did wrong?
