This is not an actual issue on the standby side, but instead a RMAN config on primary.

RMAN>  show SNAPSHOT CONTROLFILE NAME;
RMAN configuration parameters for database with db_unique_name TEST19C are:
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/19c/dbhome_1/dbs/snapcf_test19c1.f'; # default
RMAN>

Since primary is a RAC DB, snapshot control file needs to be located on a shared location, so lets change to:

RMAN> CONFIGURE SNAPSHOT CONTROLFILE NAME TO  '+DATA/TEST19C/CONTROLFILE/snapcf_test19c1.f';
new RMAN configuration parameters:
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '+DATA/TEST19C/CONTROLFILE/snapcf_test19c1.f';
new RMAN configuration parameters are successfully stored
RMAN>

After this, duplicate completed ok.
