in my debug I see that client received config from server

Then a copy of NodeInfo without sslService is first created, then another instance with sslService is created in AbstractBucketConfig constructor. However when Conductor code throws NPE
NodeInfo node = config.nodeAtIndex(index);
|
for (DcpChannel ch : channels) {
|
InetSocketAddress address = new InetSocketAddress(node.hostname().nameOrAddress(),
|
(env.sslEnabled() ? node.sslServices() : node.services()).get(ServiceType.BINARY));
|
config.nodeAtIndex(index) call returns the NodeInfo instance without sslService, causing a null in map get.
