Migrated to OCI Autonomous Database 19c. Error when accessing data dic tables from Proc

We have migrated to OCI Autonomous Database 19c.

The following SQL work outside SP run by user USR:

select 'ALTER INDEX '||INDEX_NAME||' REBUILD;' stm from sys.dba_indexes d 

    where d.owner='USR' and status <> 'VALID'  

    and status <> 'N/A' ;

When in a pros the same statement gives an error when compiled by the same user USR:

PL/SQL: ORA-00942: table or view does not exist

CREATE OR REPLACE procedure tt.FixingInd

as

   CURSOR c1 IS

    select 'ALTER INDEX '||INDEX_NAME||' REBUILD;' stm from sys.dba_indexes d 

    where d.owner='USR' and status <> 'VALID'
