Hey,

the error comes from a missing admin setting. Are you sure you have configured the admin settings and groups described here: https://github.com/csoc-de/Shifts/blob/master/docs/README.md

[Pedulla]

I'm getting this error when I go to the admin setting for Shifts.

Freshly installed on 27.1.5

[csoc-kevink]

If it is the settings page there should be an error in the console of your browser. Can you show me the output of your browser console?

[fakman0]

I tried to make the necessary authorizations, but I don't know if I did it right. The document is insufficient. The Shift authorization page opens, but there is nothing worth changing. Could you give more detailed information? I don't see any errors in the console.

[csoc-kevink]

When it's the error show above in the picture, then there might be missing groups or shift types that are not configured yet. privatemaker updated the documentation and pointed out which nextcloud groups need to be created: https://github.com/csoc-de/Shifts/tree/master/docs Created the nextcloud groups "Analyst", "Shiftsadmin" and "Level 1". Then create a shift type and you should see empty shifts in the app.

[nilleholger]

Same problem here. Created 3 groups with my acount but still no data

[nilleholger]

How do i create a shift type without fetching any data

[csoc-kevink]

That are the nextcloud groups in my test instance:

And this is the shifts configuration in the admin section:

Be aware that the group names are case sensitive! As I see, I might have made a mistake in my last post. The default value for the shift admin group is "ShiftsAdmin" not "Shiftsadmin". Sorry for that one...

[csoc-kevink]

Does the app now works?

[gardinenstange]

nope.....still the same problem here

[csoc-kevink]

Hi,

can you double check if all the group names you entered are the exact same? The App/Nextcloud are case sensitive and will not recognize 'analysts' as 'Analyst'...

[WNYmathGuy]

The groups to be created are done in https://sd.fqdn.tld/index.php/settings/users After creating the groups, and adding users to the newly created groups, go back to the settings page to overwrite the defaults https://sd.fqdn.tld/index.php/settings/admin/shifts While you're there also overwrite the Organizer defaults with real user info.

[noci2012]

Anyway...... Tried newest version on Nextcoud 29.....

Created groups as in the example: with Analyst as it is hard coded..... (copy/pasted from the source!).

The app fails in getAllAnalysts on line 189. With an access though a null pointer.
Inserting the following code:

            $group = $this->groupManager->get($groupName);
            if ($group == null ) {
                    logger("shifts")->error("Missing group $groupName");
                    return 404;
            }
            $users = [];
            $result = $group->getUsers();

Shows the message: Missing group Analyst

It does show up in the Users entry... For some reason it is missed.... by the group manager:

BTW Sprinkling such logger messages in the text might give people clues on what happens. Also loaded on this system:

GroupFolders & Autogroups. Disabling or removing Autogroups makes no difference.

[csoc-kevink]

Hi @noci2012,

thank you for the detailed report. We try to fix this issue for nextcloud 29.

We've scheduled a version 2 of the app in the near future. We want to rewrite the whole backend since it is a little 'ugly' and cannot keep up with our planed features. The logging will also be much more detailed then. For the frontend we want to wait until the nextcloud-vue library is available for Vue3.

[comradeferret]

I'm still getting the same issue in the present version 1.9.9, on a Docker install (logs referring to a null pointer in line 189). Stayed with the default group/string values, as I just want to use it as a proof of concept for my bosses. Any chance this has been fixed? I've double checked the group names and string names in the admin panel.

Exception Call to a member function getUsers() on null in file '/var/www/html/custom_apps/shifts/lib/Controller/ShiftController.php' line 189

[brownium]

I created the groups Shiftworkers, Shiftadmin, and Skillgroups. I don't understand what the "Default" column represents, so I tried creating a user with those names and adding them to the groups. ("Level 1" seems like a weird name for a user, though).

And what is meant by "Additional Strings" and where am I supposed to put them?

[csoc-kevink]

Hi brownium,

in the settings section you need to enter the exact id of the groups. The name is not necessarily the same as the id. To get the correct id, click on the group and look into the URL of your browser. There should be the correct id of the group.

Skill groups should just represent different skill levels for the users. If you dont need that feature, just create one group and put all your users into it (and the main Shiftworkers group)

Here a small guide:

• Create a group for you shiftadmins
• Create a group for all users that should use the app (shiftworkers) and put all users that should use the app into it
• Create a skill group (Level 1) and put all users that should use the app into it

Where did you find "Additional Strings"?
