SOLVED: Javascript - iterating over aspects

[fx3000se]

I would like to iterate over the aspects of a space:

for each (aspect in space.aspects){…}‍‍‍‍‍‍

For whatever reason this throws an exception.
Unfortunately the error text is not really helpful

Failed to execute script 'workspace://SpacesStore/956ba79e-5cc5-4ee7-a389-99a8db00e8aa': null‍

What am I missing?

[fx3000se]

space.aspects‍

causes already an exception. Is the "aspects" member not accessible?

[fx3000se]

SOLUTION:
as of Alf3 the member is named "aspectsSet", not "aspects"
