android retrofit rxjava java

I'm working on a project and hit a roadblock. Quick question that's been bugging me - I'm currently integrating Retrofit with RxJava for network calls in my Android app, but I'm working with an scenario when trying to parse the response from the server. I've defined my API service and the data models, but every time I make a request, I receive the following behavior: `java.lang.RuntimeException: Unable to parse response body`. Here’s a snippet of my API service interface: ```java public interface ApiService { @GET("users") Single<List<User>> getUsers(); } ``` And this is my Retrofit setup: ```java Retrofit retrofit = new Retrofit.Builder() .baseUrl("https://api.example.com/") .addConverterFactory(GsonConverterFactory.create()) .addCallAdapterFactory(RxJava2CallAdapterFactory.create()) .build(); ApiService apiService = retrofit.create(ApiService.class); ``` The `User` model looks like this: ```java public class User { private String name; private int age; // Getters and setters } ``` When I call `getUsers()`, I subscribe to it like this: ```java apiService.getUsers() .subscribeOn(Schedulers.io()) .observeOn(AndroidSchedulers.mainThread()) .subscribe(users -> { // Handle the user list }, throwable -> { Log.e("behavior", throwable.getMessage()); }); ``` I've checked the API response in Postman, and it returns a valid JSON array: ```json [ {"name":"John Doe", "age":30}, {"name":"Jane Smith", "age":25} ] ``` I’ve also ensured that my `User` class matches the JSON structure. I've tried using a custom `Gson` instance with customized settings, but the question continues. I also confirmed that I’m using Retrofit version 2.9.0 and RxJava version 2.2.19. Any thoughts on why the response isn’t being parsed correctly? What could I be missing? I'm working with Java in a Docker container on CentOS. Thanks for your help in advance! I'm developing on Windows 11 with Java. Any suggestions would be helpful.
