      Description

      It seems that JSON functions fail to get returned result from another function:

      select json_extract(json_object('truc',json_array('machin',4,json_object('chose','XML'))),'$.truc[2].chose') as result;
      +--------+
      | result |
      +--------+
      | "XML"  |
      +--------+
       
      select json_search(json_object('truc',json_array('machin',4,json_object('chose','XML'))),'one','XML') as Path;
      +-------------------+
      | Path              |
      +-------------------+
      | "$.truc[2].chose" |
      +-------------------+
       
      select json_extract(json_object('truc',json_array('machin',4,json_object('chose','XML'))),json_search(json_object('truc',json_array('machin',4,json_object('chose','XML'))),'one','XML')) as Result;
      +--------+
      | Result |
      +--------+
      | NULL   |
      +--------+
      

      Sould not the last query return "XML"?
