Add JsonInclude annotations to notification records to ensure proper JSON serialization by excluding absent (null/Optional.empty()) fields from the serialized output.
Motivation and Context
The
ResourcesUpdatedNotificationandLoggingMessageNotificationrecords were missing the@JsonInclude(JsonInclude.Include.NON_ABSENT)annotation, which could lead to unnecessary null/absent fields being included in the JSON output. This change ensures consistent serialization behavior across all notification types and prevents potential issues with clients that may not handle absent fields correctly.How Has This Been Tested?
Breaking Changes
No breaking changes. This change only affects the JSON serialization output by excluding absent fields, which should not impact existing functionality. Clients will receive cleaner JSON without unnecessary null fields.
Types of changes
Checklist
Additional context
This change aligns the notification records with the existing pattern used throughout the codebase where
@JsonInclude(JsonInclude.Include.NON_ABSENT)is applied to ensure clean JSON serialization. The annotation specifically handles both null values and Optional.empty() cases, preventing them from appearing in the serialized JSON output.
