max: Wrong type argument: number-or-marker-p, nil

[ahihi]

hi,

i'm loading doom-todo-ivy with (require 'doom-todo-ivy). trying to run doom/ivy-tasks fails with this error:

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
  +(nil 3)

it was working in the past, so i imagine some package upgrade must have broken it. but i've reinstalled emacs from scratch and still get the same error. any idea what could cause this?

i'm using emacs 27.1 on macOS 10.14 with ivy 20211231.1730 and projectile 20220203.1326.
