After Start "Could not fetch data"

[schaarra]

Hello,

I have try your Shits App in the NC (Version 22.2.2.0) but I get after Installation via Appcenter the Message "Could not fetch data". I can´t do anything and the there are only two Menu Entry on the right site. Do we need also the Application "npm and Node.js" before we install it over the Appcenter ?

Cheers Schaarra

Hey @schaarra, no, you dont need to install node when getting the app over the Nextcloud Appcenter. Regarding the error, could you check if there are any errors in the nextcloud error log?

Best regards

Fabian

Hello Fabian,

OK, normaly no other Application needed, if the install over AppCeneter. But I try it to install "npm and Node.js" and don´t fix the Problem.

Yes I get in the nextcloud.log a entry if I start the Shits App see >

Hey @schaarra, looking at the error message, i can see that there is something wrong with either the Settings set in the Shifts-Settings or the String given to "Name der Schichtmitarbeiter-Gruppe" in the Shifts-Settings does not match any Nextcloud group. Could you check wethere you have set a valid "Name der Schichtmitarbeiter-Gruppe"-String or wethere you have created the group given in this field?

Best regards

I use v1.8.3 on a new server (migrated nc but didnt have the shifts app)... but i get the same error could not fetch data and also the language text is german

[fkirchesch]

Hey @aljawaid, can you verify that you have set the Settings i have mentioned above and that the given groupname matches to an existing group? Regarding the german text, i have opted into defaulting the text into english, therefor i cannot yet explain this behavior, as the changing of languages on my testmachine works just fine.

Furthermore im working on another update that should at least fix the display of error messages and instead give a warning that the system couldn't find the given groupname.

Best regards

hello @fkirchesch, I realised that I should have changed the user group to users to match my users group which I did.

I noticed this error in the logging section:

Hello Fabian,

I have check the Shifts-Settings and the Groups the are no “Name der Schichtmitarbeiter-Gruppe” in the Settings look, attached >

In my mind the other Problem, after Installation the are no Group “ShiftsAdmin” and no Analyst in the User Groups, is this right ?

Also Reinstallation the Shits App 1.8.3 doesn’t help to fix the Problems…

I'm getting around with the user groups, but when i want to add a shift (shift type previously configured), I get a message "Schicht kann nicht angelegt werden" calendar "test" has been added and shared for the configured group and supposed to be synchronised once clicked

while adding shift with date, user selected disappears in menu once I want to save data

nc-version: 22.2.3

Hey @schaarra, unfortunatly the groups are not created by the app itself. You need to create them with any given name and paste this exact name into the fields in the settings window.

I have not yet found a way to automate this process and even so, there are usecases that benefit from the current behaviour of the app regarding user-groups.

Best Regards,

Fabian

[fkirchesch]

Hey @franconianmetal, could you please open another issue as this seems to be an unrelated issue. But as i understand it, the user selection doesn't save itself to the App-State and therefor isnt sent to the api once the shift is saved to the database. I will try to work on this and the original issue asap.

Best regards

Fabian

[Starkstromkonsument]

Please consider adding more informative error messages. I was stuck at the same point, because I did not create the groups. Thank You.
