TenantId missing in changeNotification resource type

Question

Hi,

We're trying to integrate change notifications for personal accounts for Outlook. While the API docs (https://learn.microsoft.com/en-us/graph/api/resources/changenotification?view=graph-rest-1.0) describe the tenantId as a required field, we receive notifications where tenantId is an empty String. This breaks our attempts to map the received JSON payload to ChangeNotificationCollection, since the **ChangeNotification.**tenantId is an UUID and will not accept an empty string. We're using microsoft-graph 5.46.0 for Java.

Thanks,

Branislav
