I am sending around 100 messages with confirmed delivery. But Acknowledgement is delayed because of which I get _OperationError: Guaranteed Message Window Closed_ after sending 50 messages. Is there a way to send more number of messages with guaranteed delivery?

Hey @Driviz, thanks for posting 😄 This line in the code sets the # of messages artificially so that the demonstration of sending messages is capped when users try it out themselves [https://github.com/SolaceSamples/solace-samples-nodejs/blob/master/src/basic-samples/ConfirmedPublish.js#L34](https://github.com/SolaceSamples/solace-samples-nodejs/blob/master/src/basic-samples/ConfirmedPublish.js#L34) If you show me your code I can take a look if you’ve modified things beyond what you’ve linked.
