Hi,

A message on guix-devel about guix refresh failing caught my eye today, and I decided to test the command and subsequently to bisect it. The error with "guix refresh --list-updaters" actually seems to be about a year old, and I have bisected the "json-invalid" error to commit 0bce74d458a343e61d054c4b25d6f67bd1086f3c "gnu: Upgrade to Stackage 20.26." from early June of last year. I've CC'ed Lars-Dominik Braun since he was the author of the stackage update commit.

Cheers,
Kaelyn
