Uploading Files in an Anonymous Upload which is an shared folder

[Putzlappeneimer]

Steps to reproduce

1. Create a folder for a group on the external storage (SMB) and share this folder with the user.
2. The user goes to his shared folder and creates a public share
3. Upload files over 5 MB into the share

Expected behaviour

There should be no error-message after the successfull Upload.

Actual behaviour

Tell us what happens instead
If the file is over 5 MB following message is shown: "Fehler beim Hochladen der Datei "LinuxUSBCreator.exe":Invalid request for /Test/LinuxUSBCreator.exe (NotFoundException). First sentence is german and just says that there was an error while uploading. Even with showing that error, the file is uploaded.

If the public share is not allowed to see the data inside the folder and just can upload following error is shown: could not upload "{filename}" The circle that it is uploading continues to spin, but nothing will happen afterwards. If i login and check the folder, the file was uploaded.

If i create a public share on the folder without using the shared folder, but instead of that going the whole path to that folder over the external storage menu, these errors dont happen. The problem for me is, that the users are not allowed to have access to the whole external storage folders, so they cant create that public link that way. I guess the only problem here, is that the uploader tries to use the wrong path here. For example:

Whole Path: /nextcloud-share/departmentA/user1
Shared Path: /user1

So if the link is created on the shared folder, he tries to write or move it in a directory which doesnt even exist. But the weird thing is that even with showing that error message, the file is moved to the right directory AND this message is not shown for files under 5 MB. I hope I explained it understandable.

I didnt tested, if that happens on folders which arent on an External Storage.

A way to prevent this error message, is instead of sharing the subfolders just mount each subfolder specially for that group and share it in the external storage menu. I tried that and the message isnt thrown.
