How do I configure fj.el?

[Ricardo Wurmus]

Hi Guix,

I would like to use fj.el to work on the Guix repositories at 
Codeberg.  I installed emacs-fj, set fj-user to "rekado", fj-host 
to "https://codeberg.org";, generated a token on the website, and 
then added an entry "machine codeberg.org login rekado secret 
[token]" to ~/.authinfo.gpg.

Now when I run "M-x fj-list-issues" I'm asked to select a 
repository.  I select "guix" and hit RET.  At this point I expect 
to see a list of issues, but instead I get this output:

   fj-get: I am Error: The target couldn't be found. Endpoint: 
   repos/rekado/guix/

I don't know how to debug this.  Could someone please tell me how 
to configure fj.el?
