嗨，我是新的mongodb，我有这个错误来当我击中这个端点localhost:3000/api/v1/tours/1
错误消息

{
    "status": "failure",
    "message": "Cast to ObjectId failed for value \"1\" (type string) at path \"_id\" for model \"Tour\""
}

字符串
Error image

exports.getTour = async (req, res) => {
  try {
    const tour = await Tour.findById(req.params.id);
    res.status(200).json({
      status: 'success',
      data: {
        tour
      }
    });
  } catch (err) {
    res.status(404).json({
      status: 'failure',
      message: err.message
    });
  }
};

这是应该给我给予具有特定id的旅游数据的函数。
我在这里附加架构

const mongoose = require('mongoose');

const tourSchema = new mongoose.Schema({
  name: {
    type: String,
    required: [true, 'A tour must have a name'],
    unique: true
  },
  rating: {
    type: Number,
    default: 4.5
  },
  price: {
    type: Number,
    required: [true, 'A tour must have a price']
  }
});

const Tour = mongoose.model('Tour', tourSchema);

型
以下是atlas数据库mongoose data中的数据
