Congratulations! Maybe you will stop writing shell scripts altogether.

For me, that error often means an extra pair of parentheses, such as
trying to evaluate a constant, but here the issue could be that http-get
returns two values. [1]
Maybe this works without an error?
(use-module (gnu) (guix modules))
(use-package-modules tls)
(define smartd-send-ntfy
(program-file "smartd-send-ntfy"
(with-extensions (list gnutls)
(with-imported-modules
(source-module-closure '((ice-9 receive)
(web client)))
#~((use-modules (ice-9 receive)
(web client))
(receive (_ body)
(http-get "https://example.com";)
body)))))
Instead of the string body, you could return a success value via
something like
(not (string-null? body))
You can look at the values in the comfort of the Guile REPL, or in Emacs
Geiser.
Kind regards
Felix
