I can reproduce it with c4372f7ebfac17236299346fe60c6ca125336b1f:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> (swh-download "https://gitlab.com/geontime/redkite.git" "v0.8.0" "/tmp/redkite")
SWH: found revision 68276b9b88491198c33b03c4188dfe7d6e5dbf2a with directory at 'https://archive.softwareheritage.org/api/1/directory/d14c0eb6801bca920d1e1baac7a4b9e2a0589728/'
SWH: object swh:1:dir:d14c0eb6801bca920d1e1baac7a4b9e2a0589728 could not be fetched from the vault
$5 = #f
--8<---------------cut here---------------end--------------->8---

The bug is that the Vault now returns 302 (redirect) in this case, which
is similar to the bug I fixed in <https://issues.guix.gnu.org/68741>.

So I’ll have to push that patch series and add a patch for ‘vault-fetch’
on top of it.
