Warning messages in read-replicas as "Missing attribute"

[yurena_mata]

Hello,
We have a cluster with 3 core nodes and 2 read_replica, in one of these read_replicas we have a lot of messages like:

WARN [c.n.c.d.SslHazelcastCoreTopologyService] Missing attribute read-replica-transaction-servers for read replica with hz id b4245732-830d-4cba-bab5-865377eba28b
WARN [c.n.c.d.SslHazelcastCoreTopologyService] Missing attribute read_replicas_database_names for read replica with hz id b4245732-830d-4cba-bab5-865377eba28b
WARN [c.n.c.d.SslHazelcastCoreTopologyService] Missing attribute read-replica-member-ids for read replica with hz id b4245732-830d-4cba-bab5-865377eba28b

Does anyone know what it means?

Regards

I'd have to look at the code to know for sure, but it sounds like maybe that read replica isn't properly connected to the cluster?

Is your config for that read replica equivalent to what you have for the read replica that doesn't have these warning messages?

Hello,
Both read_replicas nodes have the same configuration, the day this error appeared we had issues with the cluster, the leader node was constantly jumping between core nodes.
What is the best practice to do when we have this kind of errors? Restart the read_replica node?

Regards
