hugo version :
("hugo" "v0.81.0+extended" "darwin/amd64" "BuildDate=unknown")

Debug:
Debugger entered--Lisp error: (wrong-type-argument arrayp nil)
substring(nil 1)
(string-to-number (substring (nth 4 source) 1))
(let ((source (split-string (let ((temp-buffer (generate-new-buffer " temp" t))) (save-current-buffer (set-buffer temp-buffer) (unwind-protect (progn ...) (and ... ...)))) " "))) (string-to-number (substring (nth 4 source) 1)))
easy-hugo--version()
(progn (easy-hugo--version))

  ;; HACK fix easy-hugo--view
  (defun easy-hugo--version-patch ()
    "Return the version of hugo."
    (let ((source (split-string
		           (with-temp-buffer
		             (shell-command-to-string (concat easy-hugo-bin " version")))
		           " ")))
      (string-to-number (substring (nth 1 source) 1))))
  (advice-add 'easy-hugo--version :override #'easy-hugo--version-patch)

For now ,I just add the advide to use, change to (substring (nth 1 source)
