Oracle ORDS Data Service PL/SQL Procedure cannot return more than 32767 Characters to CLOB Out parameter called from Python or Postman

22. is 24.dbms_lob.append(o_json_clob,to_clob('"item_type_code":"'|| l_line_rec_tbl(j).item_type_code||'",'));
    25.dbms_lob.append(o_json_clob,to_clob('"line_number":"'|| l_line_rec_tbl(j).line_number||'",'));

I am calling above procedure from Python/Postman to get the value of o_json_clob, when the size is less than or equal to around 32767 then it is working fine but when size of o_json_clob is going more than 32767 then PL/SQL Procedure throws an error.

However same procedure works fine when called from Oracle SQL Developer. So how do I get value of this clob variable if the size is more than 32767 characters.
