Error using jsch-options -fn keys with babashka pod: "No reader function for tag object"

[lilactown]

Ran into along with #155 , trying to pass {:jsch-options {:server-host-key-fn ,,,}} while using spire as a babashka leads to the following error:

clojure.lang.ExceptionInfo: No reader function for tag object

Notably, the :server-host-key-fn is never even run AFAICT - any prn I add to it never shows up in stdout.
