我从 Node.js 将文档保存到 mongoose.js 时出错。这段代码已经运行了一段时间，但它现在导致 Javascript 对象出现问题，其键值看起来很好。

保存的是一个文档，其中一个成员是一个关联数组，为简单起见，它表示为Schema.Types.Mixed：

var formatSchema = new mongoose.Schema({
  name: {type: String, required: true},
  values: {type: mongoose.Schema.Types.Mixed, required: false}
});

当一个对象有一个像"0038-". 具体来说，是破折号-导致了问题。如果我取出这些值（用于测试，而不是为了用户满意度），它加载得很好。将它隔离到这里，现在我不知道如何进行。

[
  {
    "name": "INJURYF",
    "values": {
        "0": "No",
        "1": "Yes"
    }
  },
  {
    "name": "RFVF",
    "values": {
        "10050": "Chills",
        "10100": "Fever",
        "10200": "General weakness",
        "10250": "General ill feeling",
        "00323": "Salmonella arthritis",
        "00324": "Salmonella osteomyelitis",
        "0038-": "Other specified salmonella infections",   // PROBLEM STARTS HERE
        "0039-": "Salmonella infection, unspecified",
        "0040-": "Shigella dysenteriae",
        ...
      }
    }, ...
  ]

这是具体的错误信息，
