Can you send your config.scm? Without it, it's hard to know if there is a problem with your config.scm or the Guix mapper-devices code.

On line 24 of my config file I have declared a mapped device of type luks-device-mapping. If the config file does not contain any mapped-devices declaration `guix system reconfigure' works as expected (checked in a VM). I run GuixSD on a x86_64 machine. Greetings Diego N. Barbato
