获取配置了客户联系功能的成员列表
https://work.weixin.qq.com/api/doc/90001/90143/92576
该接口如果数据为空会直接报错，业务本身存在员工没有外部联系人的情况。这个能解决吗?
目前只是简单try catch 处理，可是还是会有错误日志头疼

        // 查询用户客户列表
List<String> externalUserIdList = Lists.newArrayList();
try {
    externalUserIdList = wxCpService.getExternalContactService().listExternalContacts(userid);
} catch (WxErrorException e) {
    WxError error = e.getError();
    //  not external contact,无客户返回空值不处理
    if (error.getErrorCode() != 84061) {
        throw e;
    }
}
