Java Jackson ignores non-existent attribute fields and goes to JSON by property name

Tag: class RET causes the BSP Sage case to exist annotated JSON

@JsonAutoDetect (fieldvisibility = visibility.any, gettervisibility = visibility.none, isgettervisibility = Visibility.none)
The purpose of this annotation is to use the property name to go to JSON.   prevent irregular attribute errors, such as app_id

@JsonIgnoreProperties (Ignoreunknown = True)
The purpose of this annotation is that the JSON-to-object is to prevent an error from passing in a JSON string that contains a nonexistent property.

Case:
