bug#37985: 27.0.50; Emacs server/client mode have error at lauching

[ccQ's Gmail <ccq777@gmail.com>]

I built emacs from github/mirror. When I lauch emacsclient after run `emacs
--daemon -q` (I use -q to exclude modes problems), there is always a
error message `undefine: KEY must be an integer, cons, symbol, or string
emacs`.

When I start emacs regularly (not in client), everything fine. Only in
server/client mode.


In GNU Emacs 27.0.50 (build 1, x86_64-apple-darwin19.0.0, NS appkit-1894.10 Version 10.15.1 (Build 19B88))
