Mongodb 错误显示行号和文件名

Question

从 mongodb 节点本机驱动程序 2.x 升级到 3.x

后出现这样的错误

Third parameter to find() must be a callback or undefined

我知道该怎么做我只需要知道它在哪个文件中。如何配置驱动程序以在出现错误时显示文件/行？

您需要做的是添加会抛出异常和堆栈跟踪的中间件

db.collection('Test').pre(/^(find|findOne)$/, action => {
  const opts = action.params[1];
  const allowedOptions = ['projection', 'sort', 'skip', 'limit', 'hint'];
  if (opts != null &&
      Object.keys(opts).find(option => !allowedOptions.includes(option))) {
    throw new Error('MongoDB driver 3.x does not allow passing projection ' +
      'as 2nd arg to find(). Use `projection` instead. Got ' +
      require('util').inspect(opts));
  }
});
