NC 13: Sharing app broken

Kay · February 14, 2018, 8:10am

The Sharing app seems to be broken.

In the web browser the files app will not show anything.
Just a spinning wheel.

Access via sync client and WebDAV seem unaffected.

If I disable the sharing app, all files are listed.
Everything is working except sharing.

The log shows this

Error: Call to a member function instanceOfStorage() on null

Possibly this is the same issue you are experiencing?

sync · February 14, 2018, 4:22pm

I upgraded from 12.01 to 13.0. A couple of my users noted this problem as well after the upgrade. I updated the version 12.05? commit https://github.com/nextcloud/server/pull/8196/files/10efe528ed2b5870329c8213bd6f3aa2e04629b5 and after a restart the users were able to access their folders again. The shared files were lost though.

Hello,

i have exactly the same problem on NC13 when i click on the “Shared” folder or run the filescan with occ.
I did rollback again to 11.07 which is the only stable version which works fine with ldap integration. All 12.x Version has also problem with ldap, iam not able to see the files. Atleast on NC13 i can see all the folders but problem with Sharing app!

Please help us to fix the issue on NC13.

I managed to get it to work somehow.

It seems that in my case there were orphaned records in my database.

Interestingly when the sharing app is enabled, the ‘occ files:scan —all’ command will abort with the same errors.

So what did I do:
I deleted every record that was causing this by taking the ‘getPathById’ value and deleted that record from the oc_filecache database.

After that, everything returned back to normal.

Nitha · February 16, 2018, 8:51am

Hello,

can you explain me what you have done exactly?
Because we have almost 1 Million entry in the oc_filecache table, its not easy to search and delete something.

Thanks!

Kay · February 16, 2018, 2:24pm

Hello Nitha
I would be more than willing to help.
But to me it seems you are experiencing a different problem.

My log contains references to the files affected (getPathById).
Using those IDs I was able to trace down the affected database records.

Your log however does not seem to contain any file references at all….

andy6d · August 14, 2018, 1:01pm

Is there any solution for that case?
I have this error to at NC Version 13.0.5 and an fresh istalled Elasticsearch Addon:
