Habit error

[Colin Baxter]

Hello,

With the latest pull of org-mode I now find habits are not displayed
correctly in agenda. The graph bar is missing, with the error

org-habit-insert-consistency-graphs: Wrong type argument:
number-or-marker-p, nil

----- Begin debugger output --

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
  (org-habit-build-graph (737610 1 737613 4 nil ".+") (24292 37530 669050 
863000) (24320 16922 669050 863000) (24329 31898 669050 863000))
  (org-habit-insert-consistency-graphs)
  (org-agenda-finalize)
  (org-agenda-list nil)
  (funcall-interactively org-agenda-list nil)
  (call-interactively org-agenda-list)
  (org-agenda nil)
  (funcall-interactively org-agenda nil)
  (call-interactively org-agenda nil nil)
  (command-execute org-agenda)

----- End debugger output --

The error does not occur with the 'built-in' Org mode version 9.3 for
emacs-27.

Best wishes,

Colin.
