Issues running utltz_upg_apply.sql to upgrade timezone

Oracle Database version 19.21

Hello,

We're trying to update the timezone for one of our databases using the following steps.

@utltz_upg_check.sql -- check script

@utltz_upg_apply.sql -- apply script, with restarts

But we're getting the following error.

INFO: Starting with RDBMS DST update preparation.

INFO: NO actual RDBMS DST update will be done by this script.

INFO: If an ERROR occurs the script will EXIT sqlplus.
