Node.js 架构配置无效：`…`在路径`ref处不是有效的类型`

您好，我想使用嵌入式填充
并将配料数组保留在配方模型中
但是出现了这个错误
搜索一些网站，但找不到答案

    throw new TypeError(`Invalid schema configuration: \`${name}\` is not ` +
    ^

TypeError: Invalid schema configuration: `Ingredient` is not a valid type at path `ref`. 

在配方模型中，我添加了配料字段，并给出了objectId类型和ref，但代码在ref中给出了错误

const mongoose = require('mongoose');
const recipeSchema = new mongoose.Schema({
    recipeName: {
        type: String,
        required: true,
        min: 2,
        max: 255,
    },
    addedUser: {
        type: {
            tpye: String,
            required: true,
            min: 2,
            max: 255,
        }

    },
    ingredients: [{
        tpye: mongoose.Schema.Types.ObjectId,
        ref: 'Ingredient'
    }]

});
module.exports = mongoose.model('Recipe', recipeSchema);

成分模型

const mongoose = require('mongoose');

const ingredientSchema = new mongoose.Schema({
    ingredientName: {
        type: String,
        required: true,
        min: 2,
        max: 255,
    },
    quantity: {
        type: {
            tpye: Number,
            required: true,
            min: 0
        }
    },
    unit: {
        type: mongoose.Schema.Types.ObjectId,
        ref: 'Unit'
    }
});
module.exports = mongoose.model('Ingredient', ingredientSchema);

您的“输入”在控制器中的“成分：”和“加法器：”中，并将其写为“tpye”。试着改变这一点

schema.OMG中拼写错误的类型我怎么没看到呢？非常感谢@Gibbs3岁的孩子，这条评论救了我一命
