Thanks, I think I get what you mean, I tried a way to custom the serializer
may be can pass the null
```
@Test
public void test() {
var application = TestUtils.buildApplicationCluster();
Serialization.jsonMapper().registerModule(new TestModule());
System.out.println(Serialization.asJson(application));
}
public class TestModule extends SimpleModule {
public TestModule() {
super("CustomTestModule",
VersionUtil.versionFor(SavepointInfo.class));
addSerializer(SavepointInfo.class, new
SavepointInfoSerializer());
}
}
public class SavepointInfoSerializer extends JsonSerializer<SavepointInfo> {
@Override
public void serialize(
SavepointInfo savepointInfo,
JsonGenerator jsonGenerator,
SerializerProvider serializerProvider)
throws IOException {
jsonGenerator.writeStartObject();
if (savepointInfo.getTriggerId() == null) {
jsonGenerator.writeStringField("triggerId", null);
}
}
}
```
generated:
```
"savepointInfo":{
"triggerId":null
}
```
