Subgroupfolder upload error

[yesbkz]

Hi all,

I Have a issue, with following scenario:

Admin create GroupFolder A for Group A - with Write/Share permissons
User A member Group A
User B not member of Group A

User A create a Sub folder SubFolderB in GroupFolder A and Share with full permissions to User B.

User B uploads files to SubFolder B with error: Internal Server Error.

Files doesn't showing in Web Interface, but showing on file system level.

Logs files have following:

"Error","Message":"Call to a member function getPath() on null","Code":0,"Trace":"#0 \/var\/www\/nextcloud\/lib\/private\/Share20\/ShareHelper.php(51):

I have a very similar issue - same scenario as @yesbkz described with users A, B, groupfolder and subfolder. I can't upload files from the Windows desktop client. However, the error messages I see in the logs are smiliar, but not identical to what @yesbkz is observing (debug log enabled):

What I wonder: Why is the part /groupfolders/8/ contained twice in some logs above?

Nextcloud Server Version: 12.0.2
Group Folders Version: 1.1.0
Windows Client Version: 2.3.2

I'll be glad to provide more info if required!

@stjosh does upload work as expected from the web UI?

[stjosh]

@putt1ck Thanks for the follow-up. Uploading over the Web-UI also does not work. Here's the two log lines this experiment yields:

{"reqId":"Wdu7ldkaOjsAATSzYO8AAAAB","level":3,"time":"2017-10-09T18:10:43+00:00","remoteAddr":"X","user":"test","app":"PHP","method":"PUT","url":"\/remote.php\/webdav\/Test\/Abend-GD.pages","message":"Undefined offset: 0 at \/home\/XXX\/www\/YYY\/lib\/private\/Share20\/Manager.php#1370","userAgent":"Mozilla\/5.0 (Macintosh; Intel Mac OS X 10_13_0) AppleWebKit\/537.36 (KHTML, like Gecko) Chrome\/61.0.3163.100 Safari\/537.36","version":"12.0.3.3"}

I.e., it seems that only the last two lines of my previous log are triggered "again" in this case.

I think is related to #55 - given that is a broader umbrella issue, I think we should close this and work on that.

NB from the tests done on #55 a workaround is to use share by link, which seems to work fine, and may be a more appropriate solution in general (for group folders)

This should be fixed with nextcloud/server#7137
