GNU/GUIX fails to locate custom modules specified in a manifest - guix

Question

I'm trying run guix package install for following manifest:
(specifications->manifest
'("noguix-hugo" ;; A CUSTOM MODULE implemented in /module/root-1/site-lisp/nonguix-hugo.scm
"go"))
The custom module in the manifest is declared as follows:
(define-module (nonguix-hugo)
;; implementation detail
;; ....
)
And the installation command looks like:
guix package --load-path="/module/root1/site-lisp" \
--load-path="/module/root-2/site-lisp" \
--manifest="/path/to/manifest.scm" \
--profile="/path/to/profile"
The command fails with error message:
guix package: error: noguix-hugo: unknown package
However, building the noguix-hugo using guix build command works just fine
guix build --load-path="/module/root1/site-lisp" \
--load-path="/module/root-2/site-lisp" \
nonguix-package
# The command builds and outputs the module location as expected
# /gnu/store/7js349wb17371225njzll9gma8kmwf-nonguix-hugo-1.0
My question:
Why does Guix succeed to locate the module when building it,
but can't seem to locate it when specified in a manifest file.
I even tried adding a (use-modules (nonguix-hugo)) to the manifest and setting GUIX_PACKAGE_PATH as specified in[1], yet the install still fails.

Answer 1

Okay, turns out this was a typo in the manifest:
(specifications->manifest
'("noguix-hugo"
"go"))
which should be corrected to:
(specifications->manifest
'("nonguix-hugo" ;; <= this line
"go"))
Sheesh!....
