Модифицировать при сбое, но вернуть http

Question

Я кодирую метод, который возвращает 1 запись из БД, у меня есть аналогичный метод, который возвращает все записи, и он работает должным образом, но при возврате 1 записи происходит сбой !!

public class UpdateIssueActivity extends AppCompatActivity {
IssueModel mIssuesList;
ImageView imgView;
ApiInterface apiInterface;

private static final String TAG = "UpdateIssueActivity";


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_update_issue);
    Log.d(TAG, "got into UpdateIssueActivity");


    int Id = getIntent().getIntExtra("IssueId", 0);

    apiInterface = ApiClient.getClient().create(ApiInterface.class);
    Call<IssueModel> call = apiInterface.GetIssue(Id);

    call.enqueue(new Callback<IssueModel>() {
        @Override
        public void onResponse(@NonNull Call<IssueModel> call, @NonNull Response<IssueModel> response) {
            if (response.isSuccessful()) {
                Log.d(TAG, "got inside onResponse");
            }
            else {
                    Toast.makeText(UpdateIssueActivity.this, "Failure while requesting token", Toast.LENGTH_LONG).show();
                    Log.d("RequestTokenCallback", "Code: " + response.code() + "Message: " + response.message());
            }
        }

        @Override
        public void onFailure(Call<IssueModel> call, Throwable t) {
                Toast.makeText(UpdateIssueActivity.this, "onFailure", Toast.LENGTH_SHORT).show();
                Log.d(TAG, "inside onFailure");
        }
    });

}
}

Answer 1

во время отладки показывает, что оно переходит к

onFailure(Call<IssueModel> call, Throwable t)

Я добавил

t.printStackTrace();

, поэтому он показал эту ошибку

    java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2 path $

У меня была проблема с JSON как android получил его как массив, когда я изменил его на JSON Объект со стороны сервера работал нормально
