Cassandra c# driver ServerErrorException while executing create cql statement

I am getting Cassandra task timeout error while executing

CREATE TABLE IF NOT EXISTS subscriber.packagestats (packageid text PRIMARY KEY, numaccounts counter);

LOGS

Cassandra.ServerErrorException: java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.NullPointerException at Cassandra.Tasks.TaskHelper.WaitToComplete(Task task, Int32 timeout) at Cassandra.Session.Execute(IStatement statement)

Query Consistency level is set to ALL

Used Cassandra c# driver version is 3.0.5

It was working fine until now but suddenly it starts throwing the exception , I also tried to increase the timeout upto 1 minute but still the problem persists.

Any help would be appreciated ?

I found that schema update/create was triggering race condition issues in the Cassandra version that we use (3.0.5). Schema changes in Cassandra are every sensitive and error prone. Strong consistency was only added in version 4 issues.apache.org/jira/browse/CASSANDRA-10699 Look here: stackoverflow.com/a/41269542

So I upgraded to version 4 and it solved the problem.
