Garnet Cluster Replication and Failover with a Single Master Node - CLUSTER FAILOVER is not working as expected in the opposite scenario

Garnet Cluster Replication and Failover with a Single Master Node - CLUSTER FAILOVER is not working as expected in the reverse scenario.

If the master node goes down and the slave is promoted to master using the 'CLUSTER FAILOVER' command, when the newly promoted master goes down, the current slave is not promoted to master. Instead, running the 'CLUSTER FAILOVER' command raises the error: '(error) ERR Node is not configured as a REPLICA.'

Solution found. Once the downed node is back up, We need to replicate the current master node with the recently recovered one, then perform the failover operation. It is working now.
