Server build: 7.0.0-5161
- Tried opening a bucket object with waitUntilReady call.
- Initially seen `com.couchbase.client.core.error.UnambiguousTimeoutException` exception (JCBC-1806). So did a retry of bucket connect request after 2mins of sleep.
- During this time observed 'java.lang.IllegalStateException' with reason :: "Against pre 6.5 clusters at least a bucket needs to be opened!" on the 7.0.0 server
Note: Seen very rarely in functional tests and not enabled debug / info logs when this error was encountered
