Formatter error with json_value when using variable as a path

declare 
  l_json varchar2(4000):='{"questionnaires":[{"section":"data"}]}';
  l_json_path varchar2(4000):='$.questionnaires[0].section';
begin 
    dbms_output.put_line( json_value(l_json, l_json_path) );
end;

The PL/SQL code is correct and executes successfully.

Thanks. I see this and will log it.
