You are required to:

1. Document APIs on Swagger. a. REST API and a GraphQL API to GET category list. If the parent_id is given it should return only the child categories b. REST API and a GraphQL API to get a list of products by state and transfer the state.
2. Design a proper class structure for handling the product state changes. You may use a matching design pattern (e.g. State Design Pattern). Proper exceptions should be thrown if there is an attempt to make invalid states. (e.g. draftProduct->sold() should not be allowed)
3. Implement unit testing for above APIs
4. Develop the REST and GraphQL APIs for above.
