我尝试从csv文件以编程方式上传到mongodb。我已经尝试了所有其他解决方案，并确保我的ip被列入白名单，连接正确建立。
我仍然得到这个错误：创建城市时出错MongooseError：操作countries.findOne()缓冲在10000 ms后超时
下面是我的代码，我运行它从命令行.

const csv = require('csv-parser');
const fs = require('fs');

// Example usage:
importCitiesFromCSV('./testData.csv');

下面是csv，只是一些示例数据来测试它：

位置，，名称，，国家/地区，，描述，，cjLink“Calgary，阿尔伯塔，Canada”，，Canada，，，“渥太华，安大略，Canada”，，Canada，，，，，
