android retrofit json aws Java

I'm attempting to set up I'm working on a project and hit a roadblock. While reviewing some Android code meant for a project that interacts with our AWS-hosted REST API, I stumbled upon an unexpected issue with JSON parsing. The project utilizes Retrofit 2.9.0 and Gson for serialization, but there seems to be a mismatch between the expected and received JSON structures. Here's a snippet of the problematic code: ```java public interface ApiService { @GET("/items") Call<List<Item>> getItems(); } ``` The `Item` class looks like this: ```java public class Item { private int id; private String name; private String description; // Getters and setters } ``` However, the API returns: ```json [ { "itemId": 1, "itemName": "Sample Item", "itemDescription": "A description of the item" } ] ``` I attempted to add a custom serializer to map the JSON fields to the `Item` class, but that approach felt overly complicated given that we want to maintain simplicity in our codebase. I also considered using `@SerializedName`, but I’m not sure if it can accommodate this level of renaming since the fields differ completely. Should I refactor the `Item` class to match the API response or adhere to our existing model? Also, when running unit tests, the mock responses return `null` for our fields, which complicates things further. How should I approach this? Is there a more elegant solution to handle this JSON structure discrepancy while keeping the code clean and maintainable? I'm working on a application that needs to handle this. I'd really appreciate any guidance on this. This is part of a larger REST API I'm building. Any pointers in the right direction?
