I expect that feature.getAttribute("the_geom") should get your geometry
in this case.
Your original method should also work, so it might be a bug, or
something unusual about your feature. You should not need to know the
name of the geometry of it has been configured correctly as the default
geometry.
Is this feature from a database?
Kind regards,
Ben.
