When I try to load kubel.el, it fails here:

(define-transient-command kubel-exec-popup ()
  "Kubel Exec Menu"
  ["Actions"
   ("!" "Shell command" kubel-exec-pod-by-shell-command)
   ("d" "Dired" kubel-exec-pod)
   ("e" "Eshell" kubel-exec-eshell-pod)
   ("s" "Shell" kubel-exec-shell-pod)])

When I try to evaluate that, I get
