RMAN - Backup and List of backup in same block

Hi

We are trying to run RMAN backup (Oracle 10g R2) and at the end, get a report of the backup using the following

run {
delete noprompt backup;
backup database plus archivelog delete input;
list backup;
}

But when we execute this, it gave us the following error


RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
