Unable to increase size of the cluster when Medusa backup enabled

Hi, currently i am testing Medusa backup and restore with k8ssandra-operator version 1.5.2, 1.7.0 and i have noticed that when i try to increase the size of an existing cluster, lets say for example 3 node cassandra cluster to 4. The new pod gets deployed and throws an error as below.
