I think g-exp needs to be a single expression. In other words, add `begin' in there. In your code you are basically trying to apply result of `(use-modules ...)' to result of `(http-get ...)'. Since use-modules do not return anything, you get the error above. You can test it using just plain guile and you will get the same error: guile -c '((use-modules (web client)) (http-get "https://example.org"))' I think this should work: (define smartd-send-ntfy (program-file "smartd-send-ntfy" (with-extensions (list gnutls) (with-imported-modules (source-module-closure '((web client))) #~(begin (use-modules (web client)) (http-get "https://example.com")))))) Your original code: $ guix repl Loading Guix REPL meta-commands...
