I have been following aws-sdk for javascript to execute sql queries on redshift cluster but haven't been able to connect.

Can someone guide me regarding module to use for redshift connection in javascript (except node-redshift) or share a skeleton code with proper parameter names?

Using @aws-sdk/client-redshift

const RedShiftClient = new RedshiftClient({region:'us-west-2'});
const params = {
  ClusterIdentified:'clustername-xxx-aws.com',
  NodeType: 'nodetype',
  MasterUsername:'user',
  MasterPassword:'password',
  ClusterType:'clustertype'
};

const command = new AcceptReservedNodeExchangeCommand(params);
redshiftClient.send(command)
.then(res=>{
//dosomething
})
.catch(err=>{
console.log(err);
});

Receiving error : 2 validation errors found: Value null at 'targeReservedNodeOfferingId' failed to satisfy constraint. Member cannot be null. Value null at 'reserverNodeId' failed to satify constraint. Member cannot be null.
