Errors while running SQLT (XTRACT method)

Hi,

     I am getting the errors while running sqlt (XTRACT method):

sqlt$a: *** i:"EXPLAIN PLAN FOR" this SQL errored out when executed connected as "ARWACPT". Always execute SQLT connected as the application user.

sqlt$a: *** i:ORA-00905: missing keyword

The tool was executed under the correct ID:

  4  SQL>SELECT USER FROM DUAL;

  5  USER

  6  ------------------------------

  7  ARWACPT

It looks like the error originates in install/sqcpkgi.pkb file:

BEGIN

        l_error := NULL;

        l_string := 'EXPLAIN PLAN SET statement_id = '''||sqlt$a.get_statement_id_c(p_statement_id)||''' INTO &&tool_repository_schema..sqlt$_sql_plan_table FOR';

        l_sqltext := SYS.DBMS_LOB.SUBSTR(sql_rec.sql_text_clob_stripped); -- first up to 32666 characters
