java.lang.IllegalStateException使用改造

Question

当我运行它时，我的应用程序出现错误：

com.google.gson.JsonSyntaxException：java.lang.IllegalStateException：预期为BEGIN_OBJECT但在第1行第1行路径为STRING

但我不知道如何解决它，即使我看到了一些解决此错误的解决方案，但不知道在哪里编辑或如何，你能帮助我吗？

这是我的改造部分机智服务器响应：

   Gson gson = new GsonBuilder().setLenient().create();

    OkHttpClient client = new OkHttpClient();

    Retrofit retrofit = new Retrofit.Builder().baseUrl(Constants.BASE_URL).client(client).addConverterFactory(GsonConverterFactory.create(gson)).build();

    final RequestInterface requestInterface = retrofit.create(RequestInterface.class);
    User user = new User();
    user.setEmail(ProfileFragment.Global.email);
    final ServerRequest request = new ServerRequest();
    request.setOperation("check");
    request.setUser(user);



    handler = new Handler();
    runnable = new Runnable() {
        public void run() {

            Call<ServerResponse2> response1 = requestInterface.check( ProfileFragment.Global.email );

            response1.enqueue( new Callback<ServerResponse2>() {
                                  @Override
                                  public void onResponse(Call<ServerResponse2> call, retrofit2.Response<ServerResponse2> response1) {

                                      ServerResponse2 resp = response1.body();



                                          Toast.makeText( BService.this, resp.getResult() , LENGTH_LONG ).show();
                                      Toast.makeText( BService.this, ProfileFragment.Global.ID , LENGTH_LONG ).show();
                                      Toast.makeText( BService.this, ProfileFragment.Global.Mylat , LENGTH_LONG ).show();
                                      Toast.makeText( BService.this, ProfileFragment.Global.Mylong , LENGTH_LONG ).show();





                                      if (resp.getResult().contains( "true" ))
                                      {


                                          Call<ServerResponse2> response2 = requestInterface.track( "123456"  , ProfileFragment.Global.Mylong, ProfileFragment.Global.Mylong, "56" );

                                          response2.enqueue( new Callback<ServerResponse2>() {
                                              @Override
                                              public void onResponse(Call<ServerResponse2> call, retrofit2.Response<ServerResponse2> response2) {

                                                  ServerResponse2 resp = response2.body();

我的界面：

@GET("project5/web/")
Call<ServerResponse2> check(@Query("email") String email );
@GET("project5/web/track/")
Call<ServerResponse2> track(@Query("id") String id,@Query("long") String longg, @Query("lat") String lat  , @Query("battery") String battery);
