Faces that you reference from org-agenda-deadline-faces should exist and
should be valid faces. However, it does not look like your
`org-agenda-deadline-past' and `org-agenda-deadline-today' faces are
defined correctly. You might have used malformed face declaration.

May you show how you define these custom faces in your config?

I do not see any problem in how org-agenda handles this variable. I
suspect that the problem is in your config.

If you think that the problem is on Org side, please provide a minimal
reproducer starting from emacs -Q. See
