節點/ MongoDB的JSON空數組錯誤

Question

我最近升級到5.4的節點和MongoDB 2.1.4驅動程序的節點，我有以下問題：

我有一個包含這樣的事情叫做buildings.json文件：

{ 
    "military_base": { 
     "type": "military", 
     "level": 0, 
     "maxLevel": 25, 
     "upgrade": true, 
     "targetEnvironment": [], 
     "timeUntilBuilt": 0, 
     "costCoef": 0.4, 
     "requiredResearches": [ 
      "foo#4", 
      "bar#1" 
     ], 
     "requiredResources": [ 
      "cash", 
      "metal", 
      "palladium" 
     ], 
     "inProgress": 0, 
     "queue": [] 
    }, 
    "aqua_center": { 
     "type": "industrial", 
     "level": 0, 
     "maxLevel": 25, 
     "upgrade": true, 
     "targetEnvironment": [ 
      "ocean", 
      "snowy" 
     ], 
     "timeUntilBuilt": 0, 
     "costCoef": 0.7, 
     "requiredResearches": [ 
      "lorem#10", 
      "ipsum#3" 
     ], 
     "requiredResources": [ 
      "cash", 
      "cristal" 
     ], 
     "inProgress": 0, 
     "queue": [] 
    } 
} 

現在，我想這個文件插入到數據庫蒙哥：

let buildings = require("buildings"); 
... 
collection.insertOne({ foo: buildings }, callback); 

如果第一"targetEnvironment"數組是空的，什麼都沒有插入，回調不是C alled，並沒有錯誤。但如果它被填充，一切都很好，回調被稱爲和文檔被正確插入... 我必須承認，我不知道如果問題是與Node或MongoDb驅動程序有關...

有人能幫助我嗎 ？

哦...因爲我有一個64位的Windows，我安裝了64位nodejs版本，問題來自於這裏... 32位，沒有錯誤！ ：o

#!/usr/bin/env node 

const mongodb = require("mongodb"); 
const MongoClient = mongodb.MongoClient; 
const ObjectID = mongodb.ObjectID; 

MongoClient.connect("mongodb://127.0.0.1:27017/test", function(err, db) { 
    if (err) { 
     throw err; 
    } 

    var collection = db.collection("test-insert"); 
    collection.insertOne(test, (err, obj) => { 
     if (err) { 
      throw err; 
     } 

     console.log(obj.insertedId); 

     db.close(); 
    }); 
}); 

var test = { 
    "military_base": { 
     "type": "military", 
     "level": 0, 
     "maxLevel": 25, 
     "upgrade": true, 
     "targetEnvironment": [], 
     "timeUntilBuilt": 0, 
     "costCoef": 0.4, 
     "requiredResearches": ["foo#4", "bar#1"], 
     "requiredResources" : ["cash", "metal", "palladium"], 
     "inProgress": 0, 
     "queue": [] 
    }, 
    "aqua_center": { 
     "type": "industrial", 
     "level": 0, 
     "maxLevel": 25, 
     "upgrade": true, 
     "targetEnvironment": ["ocean", "snowy"], 
     "timeUntilBuilt": 0, 
     "costCoef": 7, 
     "requiredResearches": ["lorem#10", "ipsum#3"], 
     "requiredResources" : ["cash", "cristal"], 
     "inProgress": 0, 
     "queue": [] 
    } 
}; 

如果我嘗試插入此文檔，它將不會被插入，因爲第一個costCoef屬性是一個浮點數。如果它像時間戳那樣大，它也會失敗。
