Function void: json-serialize, json-parse-buffer in Emacs 29.3

[beacoder]

My emacs version is 29.3, I found that both json-serialize and json-parse-buffer are not defined in this version.
could u please help to fix this issue ?
thanks.

sugguestions:
json-serialize could be replaced with json-encode,
while json-parse-buffer could be replacted with json-read-from-string.

Hey @beacoder, thanks for the hint here, I was having a similar issue with emacs 29.1 and an underlying package plz-media-type (not sure if that's used in codeium.el or not).

Turns out I wasn't ./configureing emacs with the --with-json flag. There's a few other steps involved but this site helped a lot: https://www.masteringemacs.org/article/speed-up-emacs-libjansson-native-elisp-compilation particularly the libjansson stuff.
