OK, can you be more specific?  ‘Invalid field specifier’ on its 
own doesn't tell us anything.

I pasted my previous example into my own system.scm and it built 
fine:

(operating-system
…
(bootloader (bootloader-configuration
             (bootloader grub-efi-bootloader)
             (target "/boot/efi")
             (theme (grub-theme
                     ;; This probably makes little sense in 
                     practice,
                     ;; unless your image suits the default 
                     colours:
                     (inherit %default-theme)
                     (images (list (grub-image
                                    (aspect-ratio 4/3)
                                    (file (local-file 
                                    "/home/…")))))))
             (timeout (seconds 1)))
…)

What does your operating-system's (bootloader …) field look like, 
and what did Guix actually say?

Kind regards,
