Bug description

After Upgrade to 28.0.2 RC1: When dragging multiple files into Nextcloud for upload only one file will be uploaded if I use Edge. On Firefox, all files will be uploaded.

This only happens with the Blink engine (Chromium, Edge, Opera), Firefox is not affected

Steps to reproduce

1. Open target folder in Nextcloud in Edge
2. Drag multiple files for upload onto the upload area
3. Check which files have been uploaded

Expected behavior

All files should be uploaded.

Hey, thanks fr the reprt :)
When you say on Edge, have you tried other browsers and they're working? Or you only tried it on Edge

The error occured on Microsoft Edge 120.0.2210.91
Firefox 121.0.1 works fine

[bravedave]

I've just upgrade to 28.02 and am seeing a similar issue

If I upload using the New > Upload files method - no issue
If I upload via Drag & Drop, only the first file is uploaded

I'm using Brave, and have checked in Chrome - same result

Brave is Version 1.62.156 (latest) on Win 11

[skjnldsv]

I can reproduce the issue
Let's wait for #43267 and move on from here! 🚀

[arnowelzel]

I agree that the current solution using a "drag & drop" area is a worse experience compared to how it was before.

Having a visual indicator as feedback that the Nextcloud file manager will accept the dropped files as upload is OK, but only accepting them in a limited "drag here" area is the complete opposite to how desktop file managers work. Older version of Nextcloud accepted files anway in the viewport and not just in certain spots.

[susnux]

This bug is still present in 28.0.3 (Edge + Chrome, Win 10).

Yes as you can see the bug is still open (!) meaning it is not resolved. This is a blink engine issue and we need to find a workaround for broken blink browsers like Chrome, Chromium, Edge and Opera.

In the meantime use Firefox or wait for this issue to be resolved.

[camouflage81]

When drag and drop a file, the system no longer checks whether it already exists. The file on the server is simply overwritten.

Closed as completed ... with all the good suggestions marked as spam ignored ...

This issue is about drag-drop only uploading one file and this issue is fixed now :)
Feel free to open new issues with bug reports or feature requests but it makes no sense to put that into a completely unrelated issue report.

This issue is not fixed in 28.0.3, and was about dragging and dropping multiple files, of which only one gets uploaded - which is still the case in 28.0.3:

Guess we continue here? #44390

[skjnldsv]

With 2 clicks you can see that the fix is within 28.0.4

[SergioRius]

I'm on 29.0.5 and this issue still reproduces for me on Firefox-based browser (Floorp) and Chrome-based browser (Vivaldi).
I would bet that I didn't happen with the last of 28s.

[susnux]

I'm on 29.0.5 and this issue still reproduces for me on Firefox-based browser (Floorp) and Chrome-based browser (Vivaldi).

29.0.5 with Firefox - can not reproduce drag-and-drop two files and both are uploaded.
Regardless if dropped on drop zone or a folder.

Same with Chromium 128 used with Nextcloud 29.0.5. Try to clear your cache and look in the browser dev tools for error messages.

[SergioRius]

Trying to upload 5 files to a new empty folder.

1. Five images to upload
   Note: From Linux, KDE Ubuntu to Floop (Firefox)
   

2. Dragging to the upload deck
   Note: The folder is contained between a group shared folder.
   

3. The following notifications appear: ("File not found" and "File upload success")
   Edit: The error not always appears and seems unrelated.
   

4. Only the first image uploaded.
   

5. Errors on console.
   

To me it seems that they all appear after the upload.
I'm investigating the one for duplicated setting, but it's a Vue trace. Anyways I think it could be related to the configuration of PHP OPcache, that I override on ".../nextcloud/php/php-local.ini" (linuxserver docker), but still complains in admin about not being configured above the default.

The upload problem happens with files and folders, independently from it's size. I it always reproduces after the update to 29.x.x

EDIT: Uploading to a non-shared folder shows the same behaviour.

I'm using the linuxserver's docker container. Could it be that the upload depends on an external component that the maintainer may not have upgraded?

[susnux]

@SergioRius could you retry now with 29.0.6 and if that does not work also show your network tab from the dev tools?

Thanks for your help, @susnux .
As the new version was published some minutes ago I deployed and did another test with it. Unfortunately it didn't work:

The file names uploaded are DSC00334.JPG, IMG_20190422_164256.jpg and IMG_20190422_164311.jpg in a new folder at the root.
The previous error I mentioned about a file missing, it's confirmed that it's totally unrelated. I happens sometimes when I enter a folder that has images.
I usually have plenty of errors from preview generator and recognize in the log. Perhaps it has to do with this upload problem? As I see that there's a PG error in the console after the first file is uploaded, and then almost nothing more...

I'll disable recognize, PG and try again. If I don't post any results is that I also did fail.

PS: If you need something more advanced, just tell. I'm sw developer (unfortunately not php) and I'll try to give you anything you need.

EDIT: Deactivating previewgenerator and recognize didn't change anything. Only first file processed.

[susnux]

Those errors are about preview generation and should be unrelated. From the network tab there is also only one PUT. Meaning the upload is either aborted or the browser only passed one file for upload.

Could you please check for debug log messages in the dev tools?

BTW: I had this error once with Firefox - restarting Firefox helped as somehow Firefox was not correctly fetching the dragged files.

You mean the debug console? It's only throwed the error reported before:

It would be nice if that error notification function showed the setting key e.name that it's supposedly duplicated.

And there's another error about recommendation not able to load a preview. I suppose bc it's too fast to ask for it and still hasn't been generated.

BTW: I had this error once with Firefox - restarting Firefox helped as somehow Firefox was not correctly fetching the dragged files.

Unfortunately I've even rebooted the computer and made no change.
Anyways, I can drag-n-drop multiple files between folders in dolphin.

EDIT: Same result by dragging from Krusader and no imges, but three txt files.

[Knusper]

Just to make some noise, I also have the same issue with Firefox and KDE Dolphin. Drag & Drop of multiple files to other file providers just works - so it must be on nextcloud side...

[SergioRius]

As a followup, since my last update I've migrated to nextcloud-aio, still at v29.
The problem still persists on Firefox based browsers, but using Vivaldi (Chromium based) I can upload more than one file. The Aio install is one build beyond the docker install, so I don't know if as to do with it working on chrome.

[b-jordanov]

I’m experiencing the same issue with Firefox and KDE Dolphin. Dragging and dropping multiple files works fine with other file providers, so the problem seems to be on the Nextcloud's side.

[Knusper]

Seems to be an issue on Firefox side https://bugzilla.mozilla.org/show_bug.cgi?id=1914742
