• Please don't comment if you have no relevant information to add. It's just extra noise for everyone subscribed to this issue.
• Subscribe to receive notifications on status change and new comments.

Steps to reproduce

1. Create a folder and dump photos into it
2. Share the folder via link, allow "editing and upload"
3. Open the link, delete a picture directly in the list, it works
4. Click on another picture to open it, select "..." on the top right and click delete -> you are now asked for credentials, which is unexpected, because it worked without credentials in 3.

Expected behaviour

In step 4, the picture should be deleted.

Actual behaviour

Credentials are required in step 4. Cancelling the simple auth form results in a 401.

Thank you for reporing this @kalsan. I looked in to this and it seems to be caused by a missing Authorisation header when the delete is invoked from the viewer in public mode.

(The authorisation should be ${token}:null base64 encoded, at the moment no Authorisation header is sent, only a
requesttoken)

Pffff, I have been looking in to this a bit, and I think it might be best to call OCA.Files.App.fileList.do_delete("filename"). Or have some other way of reusing the functionality of the files list, there is no need to duplicate the effort of creating those requests. What do you think @szaimen and @skjnldsv ?

Hello, I can confirm this issue is still present in NC25 (25.0.3). I have two separate NC instances (one on a shared host, the other on an RPI via nextcloudpi). Both are on 25.0.3. and express the same behavior. Deleting the file from the folder view works fine, but viewing the file and deleting via the context menu results in a basic authorization prompt.
