i used sample program amqssub.js to subscribe to the topics using topic-wild-card. But its throwing below error..

 node mqEventTopic.js 'dev/base/topic/+' newmgr
Sample AMQSSUB.JS start
TOPIC STRING dev/base/topic/+
Q MGR newmgr
connection name = newmgr-***:31982
MQCONN to newmgr successful 
terminate called after throwing an instance of 'Napi::Error'
  what():  Cannot read property 'toString' of null
Aborted (core dumped)```

When I run the amqssub.js program with the same topic string parameter it works fine. Have you made any other changes to the sample beyond printing extra lines? I can see a couple of places where additional sanity checks might be made to deal with bad/unexpected parameters or certain failures, but normal running seems ok.

Yes, I modified a bit.. used fn mq.Connx instead of fn mq.Conn and i passed qMgr, cno, objects to fn mq.Conn and Passing topic string and Q manager as part of command line..

  console.log("TOPIC STRING " + topicString);
  console.log("Q MGR " + qMgr);
  const cno = new mq.MQCNO()
  const csp = new mq.MQCSP()
  csp.UserId ='xxxx'
  csp.Password ='xxxxxx'
  cno.SecurityParms = csp
  cno.Options |= MQC.MQCNO_CLIENT_BINDING
  const cd = new mq.MQCD()
  cd.ConnectionName ='xxxx.xx.xxxx:31982'
  cd.ChannelName ="CLOUD.APP.SVRCONN" 
  cno.ClientConn = cd
 mq.Connx(qMgr, cno,function(err,hConn) {
   if (err) {
     console.log("MQCONN ended with reason code " + err.mqrc);
   } else {
     console.log("MQCONN to %s successful ", qMgr);
     var sd = new mq.MQSD();
     sd.ObjectString = topicString;
     sd.Options =   MQC.MQSO_CREATE
                  | MQC.MQSO_NON_DURABLE
                  | MQC.MQSO_FAIL_IF_QUIESCING
                  | MQC.MQSO_MANAGED;

     mq.Sub(hConn,null,sd,function(err,hObjPubQ,hObjSubscription) {
       if (err) {
         console.log("MQSUB ended with reason " + err.mqrc);
       } else {
         console.log("MQSUB to topic %s successful", topicString);
         // And loop getting messages until done.
         getMessages(hObjPubQ);
       }
       cleanup(hConn,hObjPubQ, hObjSubscription);
     });
   }
});
