Debugger error on startup

[Pilgrim1379]

So emacs wasn't finding some applications that are installed on my system macOS - Big Sur and Emacs 27. So I turned on debug on error and tweaks the config for exec-path-from-shell to:

(use-package exec-path-from-shell
  :if (memq window-system '(mac ns))
  :init
  (setq exec-path-from-shell-debug t)
  (setq exec-path-from-shell-arguments t)
  (setq exec-path-from-shell-check-startup-files t)
  :config
  (exec-path-from-shell-initialize))

When I start emacs, I get the following error:

Debugger entered--Lisp error: (wrong-type-argument sequencep t)

Sorry about the formatting of the error message.

I think the error is because I'm passing the wrong argument to exec-path-from-shell-arguments. If so what argument does it expect?

[Pilgrim1379]

I figured it out (setq exec-path-from-shell-arguments '("-l")) thanks,

[purcell]

Great, glad you figured it out.
