NotificationListener getEventBody is null

Platform API Java SDK

Hello all

I'm implementing notification handler and event body values are null.

notificationHandler = new NotificationHandler();
BusinessUnitListing buList = apiInstance.getWorkforcemanagementBusinessunitsDivisionviews(Arrays.asList());
Iterator<BusinessUnitListItem> buListItems = buList.getEntities().iterator();
while(buListItems.hasNext()) {
	BusinessUnitListItem buLi = buListItems.next();
	notificationHandler.addSubscription(new AgentScheduleListener(buLi.getId()));
}
notificationHandler.connect(true);

and Listener code:

public class AgentScheduleListener implements NotificationListener<WfmAgentScheduleUpdateTopicWfmAgentScheduleUpdateNotification> {

	private String buId;
	public AgentScheduleListener(String businessUnitId) {
		buId = businessUnitId;
	}
	
	@Override
	public String getTopic() {
		return "v2.workforcemanagement.businessunits." + buId + ".schedules";
	}

	@Override
	public Class<?> getEventBodyClass() {
		return WfmAgentScheduleUpdateTopicWfmAgentScheduleUpdateNotification.class;
	}

	@Override
	public void onEvent(NotificationEvent<?> event) {
		log.debug("onEvent Topic=[{}] getEventBodyRaw={} getEventBody={}", getTopic(), event.getEventBodyRaw(), event.getEventBody().toString());
		WfmAgentScheduleUpdateTopicWfmAgentScheduleUpdateNotification ev = (WfmAgentScheduleUpdateTopicWfmAgentScheduleUpdateNotification)event.getEventBody();
	}
}

the log shows following:

2020-07-31 12:29:42.522 DEBUG 21964 --- [ ReadingThread] c.e.b.s.n.l.AgentScheduleListener : onEvent Topic=[v2.workforcemanagement.businessunits.c91f6138-209b-4321-bc3e-8c1b7afb9029.schedules] getEventBodyRaw={"topicName":"v2.workforcemanagement.businessunits.c91f6138-209b-4321-bc3e-8c1b7afb9029.schedules","version":"2","eventBody":{"status":"Complete","operationId":"734b1d51-81af-479b-a285-1f308ae5654c","eventType":"Update","result":{"id":"297bbf5e-6e7d-4692-b615-a99647f117bb","weekDate":"2020-07-27","weekCount":1,"description":"","published":true,"managementUnits":[{"managementUnit":{"id":"7d181473-f327-4bb1-a84e-03b61e7ab1e4"},"startDate":"2020-07-26T22:00:00.000Z","endDate":"2020-07-31T15:00:00.000Z","agents":[{"id":"e0c6139e-e87f-44d0-84b9-e652aebecbad"}],"agentCount":1}],"metadata":{"version":2,"modifiedBy":{"id":"09c2ffa0-47ed-4345-a4d5-2a26f7fd48c8"},"dateModified":"2020-07-31T10:29:40.968Z"}}},"metadata":{"CorrelationId":"ce4ce1c8-5c8a-47e4-982a-c1d832f7b38a"}} getEventBody=class WfmAgentScheduleUpdateTopicWfmAgentScheduleUpdateNotification {
user: null
startDate: null
endDate: null
shifts: []
fullDayTimeOffMarkers: []
updates: []
}

The WfmAgentScheduleUpdateTopicWfmAgentScheduleUpdateNotification contains all null values.

Am I doing something wrong?
Thank you

Hello

I think, I found an root cause of null content of event body.
It is because I do use wrong type "WfmAgentScheduleUpdateTopicWfmAgentScheduleUpdateNotification" to handle wfm notification event.

based on documentation and my analyses, it should be "WfmBuScheduleTopicBuScheduleNotification" because this one is matching the event structure explained in documentation.
Is there any documentation, where I can find mapping of [topics] (https://developer.mypurecloud.com/api/rest/v2/notifications/available_topics.html) to Java Classes to be used in notification handler or vice-versa?

But after changing my code to:

public void onEvent(NotificationEvent<?> event) {
		log.debug("onEvent Topic=[{}] getEventBodyRaw={} getEventBody={}", getTopic(), event.getEventBodyRaw(), event.getEventBody().toString());
		WfmBuScheduleTopicBuScheduleNotification ev = (WfmBuScheduleTopicBuScheduleNotification)event.getEventBody();
	}

I'm getting an error:

It seems to be failing on deserialization of weekDate. Any ideas?
I did update to latest API version 98.0.0 and same issue occurred.

yep. https://github.com/MyPureCloud/platform-client-sdk-java/blob/master/notificationMappings.json

It appears this is an issue with the documented schemas for the notification topics. The v2.users.{id}.workforcemanagement.schedules topic's schema describes the weekDate property as a custom type urn:jsonschema:wfm:bu:schedule:topic:LocalDate, which is an object with its own properties. This is incorrect because the value that's sent in the notification is in fact a string, not a complex object as the schema describes. This causes deserialization to fail. The notification's schema will have to be updated to reflect the correct type.

Please open a case with Genesys Cloud Care to report this problem with the schema; reporting via Care comes with SLAs and various contractual commitments that the forum doesn't. I would suggest copying my above paragraph into the case to help guide the engineer to the cause of the problem.
