我有一个 OkHttp 客户端，它使用我的自定义网络拦截器将令牌插入请求标头。

我不断收到异常

E/AndroidRuntime: FATAL EXCEPTION: OkHttp Dispatcher

我尝试用 try/catch 包围拦截器。并抛出错误以避免应用程序崩溃，但没有好的结果。

拦截器代码：

package com.edstart.tazuzu.RestAPI

import android.util.Log
import com.edstart.tazuzu.Managers.ServerManager
import okhttp3.Interceptor
import okhttp3.Response
import java.net.InetAddress
import kotlin.Exception
