对于accountType = email，email设置为唯一，对于accountType = username，username也设置为唯一。Mongodb为accountType = username发送此。键不是{ username：“username”}

"err": "E11000 duplicate key error collection: painPoint.users index: email_1 dup key: { email: null }",
{
    "error": {
        "index": 0,
        "code": 11000,
        "keyPattern": {
            "email": 1
        },
        "keyValue": {
            "email": null
        }
    }

字符串
电子邮件密钥是正确的，但取决于我首先创建的帐户。

"err": "E11000 duplicate key error collection: painPoint.users index: email_1 dup key: { email: \"[email protected]\" }",
    "error": {
        "index": 0,
        "code": 11000,
        "keyPattern": {
            "email": 1
        },
        "keyValue": {
            "email": "[email protected]"
        }
    }
}

我希望两者都返回正确的键值，我不知道是什么原因导致了这一点，因为这两个字段在模式定义中都被设置为唯一的。
我的架构

import mongoose from "mongoose";

const UserSchema = new mongoose.Schema({
  email: {
    type: String,
    unique: [true, "Email already exists"],
    required: [
      function () {
        return this.accountType === "email";
      },
      "Email is required",
    ],
  },
  username: {
    unique: [true, "Username already exists"],
    type: String,
    required: [
      function () {
        return this.accountType === "username";
      },
      "Username is required",
    ],
  },
  name: {
    type: String,
    required: [
      function () {
        return this.accountType === "email";
      },
      "Name is required",
    ],
  },
  accountType: {
    type: String,
    required: true,
    enum: ["username", "email", "google"],
  },

  password: { type: String, required: true },
  since: { type: Date, default: Date.now },
  injuries: [{ type: mongoose.Schema.Types.ObjectId, ref: "Injury" }],
});

export default mongoose.models.User || mongoose.model("User", UserSchema);
