java.lang.IllegalStateException：预期BEGIN_OBJECT但StrING在第2行第1列错误

Question

我是android编程新手。我有一个类，在这个类中，修改API调用是为了解析和显示JSON文件中的几个属性。但我得到：

Java语言lang.IllegalStateException：应为BEGIN\u对象，但在第2行第1列为字符串

好心帮忙。我搜索了答案，但没有发现JSON响应有任何问题。发布了我的JSON响应和JAVA类：

您是否使用了正确的模型来映射您的响应？应该是：

DriverRequestModel driverRequestModel = response.body();
