mongodb - 如何在mongoskin中设置安全变量？

我收到以下错误消息：

========================================================================================
=  Please ensure that you set the default safe variable to one of the                  =
=   allowed values of [true | false | {j:true} | {w:n, wtimeout:n} | {fsync:true}]     =

我已经在本地mongodb中找到了处理它的方法，但是有没有方法使用mongoskin设置safe变量？
澄清：尽管有错误，我还是能够查询数据库并将字符串输出到控制台。但是，如果我想返回变量以便将其传递给另一个函数，我将得到：

{ emitter: { _events: { open: [Object] }, _maxListeners: 50 },
  state: 1,
  options: undefined,
  skinDb:
   { emitter: { _events: [Object], _maxListeners: 100 },
     state: 1,
     _dbconn:
      { databaseName: 'titles',
    serverConfig: [Object],
    options: [Object],
    _applicationClosed: false,
    native_parser: true,
    bsonLib: [Object],
    bson: {},
    bson_deserializer: [Object],
    bson_serializer: [Object],
    _state: 'connecting',
