尝试将objectId数组添加到集合中时，转换为objectId失败错误

Question

我正在建立一个数据库，并且在测试过程中，使用伪数据时，ObjectId数组未保存在数据库中

我使用内置的mongoose函数进行了检查，当我检查它是否为object-ids时，它返回true

模式是这样的

const projectSchema = new mongoose.Schema({
  name: String,
  description: String,
  tasks: [{ type: Schema.Types.ObjectId, ref: "Task" }],
  feedBack: String
});

let Project = mongoose.model("Project", projectSchema);

const taskSchema = new mongoose.Schema({
  name: String
});

let Task = mongoose.model("Task", taskSchema);

我正在添加这样的收藏

async function dbLoad() {
  let taskArr = projectDummy.map(project => project.tasks);
  let taskCollection = [].concat(...taskArr).map(task => {
    let t = new Task();
    t.name = task.name;
    return t;
  });

  await Task.insertMany(taskCollection);

  let projectCollection = [];
  for (let project of projectDummy) {
    let taskArr = [];
    for (let task of project.tasks) {
      let data = await Task.findOne({ name: task.name });
      taskArr.push(data["_id"]);
    }
    projectCollection.push(
      new Project({
        name: project.name,
        description: project.description,
        tasks: taskArr
      })
    );
  }

  await Project.insertMany(projectCollection);
}
