發送發布請求時出現重復密鑰錯誤

我有一個架構

const VendorSchema = new mongoose.Schema({
firstName: {
    type: String,
    minlength: [3, "This field requires a minimum of 3 characters"],
    maxlength: [50, "This field requires a maximum of 50 characters"],
    required: [true, "Please provide firstName"],
    trim: true
},
lastName: {
    type: String,
    minlength: [3, "This field requires a minimum of 3 characters"],
    maxlength: [50, "This field requires a maximum of 50 characters"],
    required: [true, "Please provide lastName"],
    trim: true
},
businessName: {
    type: String,
    minlength: [3, "This field requires a minimum of 3 characters"],
    maxlength: [50, "This field requires a maximum of 50 characters"],
    required: [true, "Please provide your business name"],
    // unique: true,
    trim: true
},
businessLocation: {
    type: String,
    minlength: [3, "This field requires a minimum of 3 characters"],
    maxlength: [50, "This field requires a maximum of 50 characters"],
    required: [true, "Please provide your business location"],
    trim: true
},
IDNumber: {
    type: String,
    minlength: [5, "This field requires a minimum of 5 characters"],
    maxlength: [50, "This field requires a maximum of 50 characters"],
    required: [true, "Please provide ID Number or a passport"],
    // unique: true,
    trim: true
},
telephone: {
    type: String,
    minlength: [3, "This field requires a minimum of 3 characters"],
    maxlength: [50, "This field requires a maximum of 50 characters"],
    required: [true, "Please provide telephone"],
    // unique: true,
    trim: true
},
industryCategory: {
    type: String,
    minlength: [3, "This field requires a minimum of 3 characters"],
    maxlength: [50, "This field requires a maximum of 50 characters"],
    required: [true, "Please enter industry's category"],
    trim: true
},
email: {
    type: String,
    minlength: [5, "This field requires a minimum of 5 characters"],
    maxlength: [50, "This field requires a maximum of 50 characters"],
    required: [true, "Please provide an email"],
    match: [/^\w ([\.-]?\w )*@\w ([\.-]?\w )*(\.\w{2,3}) $/, 'Please provide a valid email address'],
    // unique: true,
    trim: true,
    lowercase: true
},
password: {
    type: String,
    minlength: [5, "This field requires a minimum of 5 characters"],
    maxlength: [1500, "This field requires a minimum of 1500 characters"],
    required: [true, "Please provide password"],
},
resetPasswordToken : String,
resetPasswordExpiry : Date
})

這是我與上述架構相關的控制器

exports.vendorRegistration = async (req, res, next) => {
try {
    const {
        firstName, 
        lastName, 
        businessName, 
        businessLocation, 
        IDNumber, 
        industyCategory, 
        email, 
        telephone, 
        password 
    } = req.body

    const vendor = await Vendor.create({
        firstName, 
        lastName, 
        businessName, 
        businessLocation, 
        IDNumber, 
        industyCategory, 
        email, 
        telephone, 
        password 
    })

    sendVendorToken(vendor, 201, res)
    
} catch (error) {
    next(error)
}
}

sendVendorToken 是一個接受這些爭論并回傳令牌的函式。這是用于捕獲重復值的錯誤中間件

    if(err.code === 11000){
    const message = "Duplication Key Error"
    error = new ErrorResponse(message, 400)
}

當我嘗試發送發布請求以創建供應商時，我收到重復密鑰錯誤。這是郵遞員 在此處輸入影像描述的結果

我不知道為什么會收到此錯誤

在此處輸入影像描述

從上圖中該欄位不存在，我已在我的架構和控制器中將該欄位名稱完全更改為行業型別，但我仍然收到索引：行業類別 1 復制鍵：{行業類別：空}“錯誤。問題可能是郵遞員還是什么?我應該重新安裝郵遞員嗎？我很困惑

uj5u.com熱心網友回復：

我過去遇到過同樣的問題，在我的情況下，我通過去mongo compass并從資料庫中洗掉用戶（在你的情況下是供應商）集合來解決問題。

如果您不想丟失供應商集合中的現有資料，您可以查詢所有供應商檔案并將它們作為 JSON 存盤在其他地方，洗掉供應商的集合，然后重新插入所有供應商的檔案
