This is not actually a bug.

We switched from Guile JSON 1.x to 3.x, which has a different
intermediate representation for JSON data structures.

swh.scm and all other modules have been modified, but when you run “guix
environment guix” you still get an environment with Guile JSON 1.x.
This leads to the test failure.

This problem disappears when you run “guix environment guix --ad-hoc
guile-json”; it will disappear when the “guix” package is upgraded to
point to the latest version of Guile JSON.
