How to fix (optional)

[Julius-Babies]

Your account seems to be linked to 11/1 - Tutorenkurs, is this correct?

[Konsl]

Yes, that's correct

[Julius-Babies]

That explains it. The app tries to connect your vpp.ID with a class with the same name which comes from the stundenplan24.de data. Such a class doesn't exist there. Do you know, if your beste.schule account is linked to multiple so-called meta-groups? Maybe one of them is JG11. For now, I can manually fix your profile in the database.

Please try to re-login in VPlanPlus.

[Konsl]

From what I can tell, there is only one meta group called 11/1 - Tutorenkurs, as you mentioned. There also exist other groups (like 11CH2) but those are not meta groups.

[Konsl]

Please try to re-login in VPlanPlus.

I am now able to successfully log in and view my grades.

[Julius-Babies]

So changing the class ids manually in my database is a workaround. Please tell your classmates to send me an email (julvin.babies@gmail.com) with their beste.schule account name and Stundenplan24.de class name if they're experiencing similar issues.
