无法在 NodeJS 服务工作者中填充猫鼬模式模型

如何解决无法在 NodeJS 服务工作者中填充猫鼬模式模型

我正在研究 MERN Stack 设置以及 Mongoose 和 Typescript。

我正在尝试在 NodeJS Service Worker 上运行一个简单的查询，以查找单个模型文档并填充其参考文档（标签）。

然而，这个查询在 Express 控制器中运行得非常好，但在 Service Worker 上却没有。

这是我的代码：

架构模型

/**
 * Question Model
 */
export interface QuestionModel extends QuestionRecord,Document {}
export const QuestionSchema: Schema = new Schema({
    title: {
        type: String,required: true
    },type: {
        type: String,description: String,tags: [{
        type: Schema.Types.ObjectId,ref: 'Tag'
    }],isDraft: {
        type: Boolean,default: true
    }
},{
    timestamps: true
})

/**
 * Tag Model
 */
export interface TagModel extends TagRecord,Document {}
export const TagSchema: Schema = new Schema({
    key: {
        type: String,name: {
        type: String,required: true
    }
},{
    timestamps: true
})

查询（在 Service Worker 中）

const question = await QuestionSchemaModel.findById(questionId,{ title: 1,tags: 1,type: 1,description: 1 }).populate('tags');

console.log('Print Tags:',question.tags);

错误
