Spring boot jackson inheritance polymorphism with child class that has same parameters - how to tell jackson what class to use

Question

I have an parent class EdgeEntity and a child class MigrationEdgeEntity extends EdgeEntity.

Child does not have any new parameters. It's used for migration when some logic is altered/different then in the normal use of EdgeEntity.

MigrationEdgeEntity in the end saved as EdgeEntity in the database.

I can use jackson annotations to make the API endpoint for migration to work. But then when I try to get EdgeEntitys from the database it fails. If I don't use the annotations the API migration end point fails.

@JsonTypeInfo(use = JsonTypeInfo.Id.DEDUCTION, defaultImpl = EdgeEntity.class)
@JsonSubTypes({@JsonSubTypes.Type(value = MigrationEdgeEntity.class, name = "migrationEdgeEntity")})

for EdgeEntity

And for MigrationEdgeEntity I have:

@JsonTypeInfo(use = JsonTypeInfo.Id.DEDUCTION, property = "type")
@JsonTypeName("migrationEdgeEntity")
@JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id")

I don't understand much about jackson. So those might be the problem but somehow they work for the API

Not sure what to try next.

I am trying to migrate an EdgeEntity to a system but there needs to be inherited and overloaded behavior. Kinda much of that actually.
