cn.jmessage.api.user.UserStateListResult.getDevices()Ljava/util/List;

服务端sdk调用查看用户状态时，本地测试没问题。放到线上，便报这个错误

{
    "timestamp": "2019-04-17 17:48:08",
    "status": 500,
    "error": "Internal Server Error",
    "message": "cn.jmessage.api.user.UserStateListResult.getDevices()Ljava/util/List;",
    "path": "/divine/jm/status"
}

异常也捕获不到
