I'm attempting to create an export mapping to include information about a related object from my currently exported object, but I can't figure out what to put in the source column. As a test, I am merely trying to output the preferred_labels for related objects, but I am confused as to whether I should be specifying the bundle name or the name of the table in the database (there is some overlap, like ca_places and ca_entities).I have tried both ca_objects.ca_objects.preferred_labels and ca_objects_x_objects.preferred_labels. I have also tried the option { "context" : "ca_objects_x_objects" }. I have a feeling I must be missing something simple here. I haven't been able to find any examples of this being done.Thanks.
