Additional info

Tested with Firefox 120.0.1 on Windows and Linux. Chromium on Linux has same behaviour.

Had a short chat about this one. @susnux proposed a solution maybe would be to not only use the drag and drop zone but allow dropping on the whole file table.

Same issue NC28.0.0 web ui crash when dragging files into the system via web

[gotton]

I confirm. Same issue here.

I can see different behavior (both firefox) : on windows, the drag and drop doesn't work at all (even in the dedicated area). On mac os x, the drag and drop works in the dedicated zone but doesn't work on the rest of the page.

Hi,

docker image "latest" has been upgraded to 28, with the broken drag and drop.

Any chance to se a fixed update soon?

[francescop75]

Hi,

I've also noticed that trying 5/6 times, going back when the upload fails and trying again, there is a chance that sometimes both files and folders are correctly uploaded, but only when using the top "drag and drop" box.
