we are seeing an issue with our Staging environment which has 8 servers, 4 with only data services enabled and another 4 with query/index services enabled. When the SDK attempts a query, we get the exception below. We normally pass in the whole list of servers in our ClusterOptions, but we have also tried just explicitly passing in a single server that has query/index services. Always get the same exception. Is it a requirement that ALL servers in your CB cluster must have data/query/index services enabled in order for the SDK queries to work?
