rpoplpush throws a conversion error when there is no entry on source list (2.0.0 beta)

Expected behavior

rpoplpush to return nil when there is no entry on source list

Actual behavior

The following error is thrown

error: "RedisClientError(baseError: RediStack.RedisClientError.(unknown context at $116964d50).BaseError.failedRESPConversion(to: Swift.Optional<RediStack.RESPValue>))"

Steps to reproduce

The following code will produce an EventLoopFuture that will fail as long as "list1" does not contain any items.

    return redis.send(.rpoplpush(from: "list1", to: "list2"))
}
