I refactored making the above four queries fail.
SELECT JSON_QUERY(jsonb '{"a":[3,4]}', '$.z' RETURNING int4range empty
object on error);
The new error is: ERROR:  cannot cast DEFAULT expression of type jsonb
to int4range.

also make the following query fail, which is as expected, imho.
select  json_value(jsonb '{"a":[123.45,1]}', '$.z' returning text
error on empty);
