Description
As described here, the addMember() function cannot be used in a script without raising an AttributeError.
I am not good enough yet to understand the decorators in every context, but it seems to me that the @cached_classproperty interferes with some (new?) features of MaKaC.common.timerExec.Alarm. The decorator obviously is supposed to hide non-existing attributes as long as the relevant class has not yet been declared in python. It is used in the declaration of the Avatar class, source:/indico/MaKaC/user.py@476d3fc1105d2c452644f1879b083805dc7bc091#L314 apparently.
I found a workaround: Add
from MaKaC.common.timerExec import Alarm #WORKAROUND (>v1.2.2)
to all my problematic scripts.
I hope some more competent programmer than me can quickly find out the right way to fix it.

Fixed in e20e3ae. Within Indico it worked because those modules have been imported somewhere before accessing the property.
