Same idea of : #36013 ? |

@sHHHk sorry for the late reponse. Could you elaborate on how to reproduce the issue? Or what you mean with "preview image link doesn't work"? Do you mean that a file shared with another user doesn't display the preview in their file list? Please provide a screenshot of what you consider broken. |
|
@sHHHk You describe error with talk app. (on my side, same issue, via web ou mobile app(android and ios)) Have you tested on files app ? (web and mobile ?) Example : If folder his shared by other(here user S) : => via web app, click on file and you see it If share via link : no preview too |
Bug description
Whenever I share a picture with another user via Nextcloud Talk for example, the user with whom the picture was shared cannot see it under their preview URL.
In my example the user who uploaded the image can view it with both of these URLs. Whereas the user who the file was shared with can only view it in his Nextcloud Talk Folder under the second URL. The server throws a 404 for the first URL.
Example for a preview URL: https://example.com/core/preview?fileId=1240931
Example for https://example.com/remote.php/dav/files/user/Talk/20210908_091635.jpg
Steps to reproduce
Unfortunately I was not able to enclose the cause of this.
I thought I could pin the issue down by disabling all apps with occ and disabling server sided encryption (which was originally enabled on my instance).
Expected behavior
I would assume that an image preview should be shown for the user who the file was shared with under the exact same link with the preview id.
In my example: https://example.com/core/preview?fileId=1240931
