I'm trying to write ephemeral data to a writable replica as described here:
https://redis.io/topics/replication
but the set command does not work as expected. I get a MOVED error response instead of an indication of a successful operation.
127.0.0.1:7003> config get replica-read-only
1) "replica-read-only"
2) "no"
127.0.0.1:7003> set fov no
(error) MOVED 11406 127.0.0.1:7002

Note that I'm on node 7003 which is a replica of 7002, but as you can see I get redirected to 7002 instead of allowing the write to add to the replica. I've configured a cluster as described by this
https://redis.io/topics/cluster-tutorial except my redis.conf contains replica-read-only no, which I verified above.
This works in a non-clustered environment with a single primary and a single replica (6380 is a replica of 6379). Everything works as expected in this scenario.
127.0.0.1:6380>set fov yes
OK

Any help on how to get this to work in redis cluster would be greatly appreciated. Thanks!
