Hm.  I thought I fixed this bug already…

Ah, you're using an old version of Guix:

  ~ λ package -A jsonschema
  python-jsonschema       2.6.0   out 
  gnu/packages/python-xyz.scm:1989:2
  …

Please guix pull and install python-jsonschema@2.6 instead.

It seems like it should be propagated, though.  I'll look into 
that.

Kind regards,
