As you might have seen on #swh-devel on irc.libera.chat, this is due to
an API change on their side, which is now fixed in
fb32a38db1d3a6d9bc970e14df5be95e59a8ab02.  Tested with the usual:

  guix build -S guile-bash --check

The API change (removing “obj_id” and “obj_type” from vault replies)
might be reverted, according to what SWH folks said on IRC.

However, other incompatible changes may happen on /api/1.  For instance,
I noticed by chance that /api/1/vault/directory, which we use in
‘request-cooking’, is marked as deprecated.  I’ll update our code to the
new API soonish if nobody beats me at it, but it’s a bummer that old
code might break anytime.  :-/  (The API is officially not considered
stable.)

Thanks,
Ludo’.
