Android 使用改型和rxjava2时会显示JSON文档未完全使用的异常

我正在使用改型和rxjava2将数据保存在数据库中。成功添加数据后，它显示以下异常：

JSON document was not fully consumed

为什么即使没有错误且我的数据已成功添加到数据库中，也会显示此异常。添加数据后，我希望显示服务器发送的成功消息，但添加数据后，将显示异常消息，而不是成功消息

在postman中显示来自服务器的成功POST请求消息之后，我已经尝试了使用postman的api

下面是我的代码：

ApiService.class

public interface ApiService {

@POST("saveData")
@FormUrlEncoded
Single<String> saveDataOnServer(@Field("Name") String Name,
                                @Field("Age") String Age);

}

public class RetrofitClient {

private static Retrofit retrofit = null;

private static final String URL = "https://example.com/";

public static Retrofit getInstance(){

    OkHttpClient okHttpClient = new OkHttpClient.Builder()
                                .connectTimeout(10, TimeUnit.SECONDS)
                                .readTimeout(10,TimeUnit.SECONDS)
                                .writeTimeout(10,TimeUnit.SECONDS)
                                .build();

    if(retrofit == null){

        retrofit = new Retrofit.Builder()
                       .baseUrl(URL)
                       .addCallAdapterFactory(RxJava2CallAdapterFactory.create())

您收到的JSON文档是什么样子的。它看起来像{“Name”：“John”，“Age”：“20”}您收到的JSON文档是什么样子的。它看起来像{“Name”：“John”，“Age”：“20”}
