Drag and drop warning in application window

[mahsashadi]

Hello. I am trying to make available drag and drop option for user in my application window, in below code:

import React from 'react';
export default function App ({win, proc}) {
  //const [basic] = React.useState(() => core.make('osjs/basic-application', proc, win));
  React.useEffect(() => {
    win.on('drop', (_, draggedData) => console.log('drag and drop happened'));
    // win.on('drop', (_, draggedData) => basic.open(draggedData));
  }, []);

    return (
      <p> test </p>
    );
}

But It does not work due to the following warning. Do you know what is the problem? (I am using the latest versions of packages)

What's the data of the drop?

A file with the aim of scanning or uploading (txt, png, exe, ...)

As in, from the file manager ?

Oops! Sorry. We only can drag and drop from file manager files by this code. I was trying files from my system. Thanks a lot!
