How to resolve Channel 'application.bischannel' has 0 subscriber(s)

Question

I was created one poller which will execute every one second and call some method to perform action but sometimes i am getting "Channel application.bischannel has 0 subscriber(s)" exception.

Here i am attaching my code:

@Component
public class BISPoller {

@Autowired
private BisAPIService bisApiService;    
    
@InboundChannelAdapter(channel="bischannel",poller = @Poller(fixedDelay = "1000"))
public String billingTransactionEventPoller() {
    bisApiService.performBillingTransactionEvent();
    return "Bill Transaction Event Execution Completed";
}

@ServiceActivator(inputChannel = "bischannel")
public void handle(String in) {
 //Logger method
}

}

Let me know how to resolve issue.
