Yes you are doing something wrong, naming an argument with a type
name(json) is not a good idea. Guessing you got caught by this:
https://www.postgresql.org/docs/16/sql-keywords-appendix.html
JSON non-reserved reserved
https://www.postgresql.org/docs/17/sql-keywords-appendix.html
JSON non-reserved (cannot be function or type) reserved
