Changes

Code generator stores the defined types (entities) in pkg.types field. This field is primarily used for keeping the list of all observed types while generating code.

But if we use the entity stored in this map and modify it in-place, for example, add that some field is required, it will change the entity stored.

If later one we use this "cached" version of entity, it will contain modified configuration which can lead to unexpected results, for example, User entity in Users.create operation will have ID field as required even though based on OpenAPI definition it is not.

Thus, it's better not to use cached entities.
