After upgrading from 12c to 19C getting ORA-01031: insufficient privileges

Hi , I am facing an issue after upgrading  from 12c to 19c. I get issues when executing the below :

BEGIN

 DBMS_SCHEDULER.define_chain_step (

  'SCHEDULE.TEST_SCHDULER',

  'STEP' || '1' ,

  'SCHEDULE.TEST_SCHDULER' || '_PGM' || '1');

END;

/

BEGIN

*

ERROR at line 1:

ORA-01031: insufficient privileges

ORA-06512: at "SYS.DBMS_CHAIN_INVOKER", line 291 -------> Introduced in 19c

ORA-06512: at "SYS.DBMS_RULEADM_INTERNAL", line 275

ORA-06512: at "SYS.DBMS_CHAIN_INVOKER", line 287

ORA-06512: at "SYS.DBMS_SCHEDULER", line 1762

ORA-06512: at line 2

I have granted execute priv to public and directly to the user executing the above.

Has anyone come across this issue?
