Weird error with customized theme (not sure what it means)

[Daniel]

Customizing the theme has been the hardest thing I’ve done on Doom Emacs and it still doesn’t quite seem to work. It’s giving now this error:

 ■  Error (doom-load-theme-hook): Error running hook "doom-apply-customized-faces-h" because: (wrong-type-argument listp doom-city-lights)

My configs.

(setq doom-theme 'doom-city-lights)

(custom-theme-set-faces! 'doom-city-lights
  '(default :background "#10151a")
  '(default :foreground "#ffffff")
  '(org-level-1 :inherit outline-1 :height 1.2)
  '(org-level-2 :inherit outline-2 :height 1.0)
  '(org-level-3 :inherit outline-3 :height 1.0)
  )

Seems like it was caused by this snippet:

 (custom-set-faces! 'doom-city-lights
   '(default :background "#10151a")
   )

changing this to custom-theme-set-faces! removes the error, but may cause huge issues on Wayland (the entire background goes white).
