Pasting the dap-mode-map keybindings from the documentation returns wrong type argument

Pasting the [keybindings](https://docs.doomemacs.org/latest/modules/tools/debugger/#keybindings,code-1--1
) to my private config.el doesn't provide these bindings and returns this flycheck error:
`Wrong type argument: proper-list-p, ("d" . "dap") (emacs-lisp)`

excerpt of my private config.el:

```lisp

(setq dap-python-debugger 'debugpy))
