Not able to perform query using vertx-db2-client with Spring Boot and getting error - spring-boot

Question

I'm trying to connect and query to DB2 using vertx-db2-client, but it is not working. I'm using Spring Boot 2.6.6 and vertx-db2-client library to perform query in reactive way. I've created a class which implements CommandLineRunner
Dependency in my build.gradle
implementation 'io.vertx:vertx-db2-client:4.2.6'
implementation 'io.vertx:vertx-reactive-streams:4.2.6'
Below is my CommandLineRunner class.
import io.vertx.db2client.DB2ConnectOptions;
import io.vertx.db2client.DB2Pool;
import io.vertx.sqlclient.PoolOptions;
import io.vertx.sqlclient.Row;
import io.vertx.sqlclient.RowSet;
import io.vertx.sqlclient.SqlClient;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.CommandLineRunner;
import org.springframework.context.annotation.Configuration;
#Configuration
#Slf4j
public class DB2DataLoader implements CommandLineRunner {
/**
* Callback used to run the bean.
*
* #param args incoming main method arguments
* #throws Exception on error
*/
#Override
public void run(String... args) throws Exception {
DB2ConnectOptions connectOptions =
new DB2ConnectOptions()
.setPort(50001)
.setHost("db_host_name")
.setDatabase("db_name")
.setUser("username")
.setPassword("password");
// Pool options
PoolOptions poolOptions = new PoolOptions().setMaxSize(5);
// Create the client pool
SqlClient client = DB2Pool.client(connectOptions, poolOptions);
// A simple query
client
.query("SELECT * FROM SCHEMA.TABLE")
.execute(
ar -> {
if (ar.succeeded()) {
RowSet<Row> result = ar.result();
System.out.println("Got " + result.size() + " rows ");
} else {
System.out.println("Failure: " + ar.cause().getMessage());
}
// Now close the pool
client.close();
});
}
}
I'm not seeing any connection issues. The error that I see right after the deployment is below:
2022-04-11 15:35:11.740 INFO 2736 --- [ main] c.h.t.p.ServiceApp : Started ServiceApp in 3.746 seconds (JVM running for 4.719)
Failure: SQLState.NET_VCM_VCS_LENGTHS_INVALID: VCM and VCS lengths are mutually exclusive but both were set: vcsLen=255 vcmLen=12336
I'm not sure what is this "Failure: **" means. Can anyone please help me understand this and how to fix. Database connection parameters are correct. I've just masked here. I was following this documentation for the example.
