google.calendar('v3').events.list finds no entries in public calendars

[hesst]

events.list finds no entries in public calendars.
I have the calandar with id de.german#holiday@group.v.calendar.google.com in my calendarlist. events.list for this id returns with error: Not Found.
For the calandar with id #contacts@group.v.calendar.google.com comes no error but no entries.
