Hi,

the parameter "rds.logical_replication=1" is only active on the instance that has the Writer role (open for read-write). When you set this parameter you will have to use the writer instance for logical replication. You can connect to the writer instance either via Cluster endpoint (recommended) or instance endpoint.

Also, do a manual reboot of the instance after you change a parameter to activate it.

Best,

Didier
