pre 5.51 - trying to import just a contact ID and add to group fails due to missing mandatory fields

At some point while testing import_to_group, I got that same error:

I thought that happened while running import_to_group, but it could be that I needed a more up-to-date base. I merged locally with head, reset DB -- then it ran cleanly.
