{
  "ok": false,
  "msg": "unexpected error: Could not locate column in row for column 'groups_name'",
  "item_name": "keypair",

Line 217 in 60e4bde

projects=row["groups_name"],

To Reproduce

1. Create a new user

$ ./backend.ai admin user add default username@backend.ai 0000

2. Create a new keypair for the user

$ ./backend.ai admin keypair add username@backend.ai default

Expected Behavior

Successfully create a new keypair for the given user.

Anything else?

It seems to be related to GraphQL or database fields.

This is being handled in #1360, and this particular fix is already cherry-picked to #1632 (648380a).
So, #1661 is a duplicate of #1360 and #1632.
@adrysn @kyujin-cho Please review and apply #1632 ASAP.
