aggregate报错

const db = cloud.database() db.collection('orders').aggregate()  .lookup({    from: 'books',    localField: 'book',    foreignField: 'title',    as: 'bookList',  })  .end()  .then(res => console.log(res))  .catch(err => console.error(err))

根据示例改造

db.collection('PRODUCT_TYPE').aggregate({})

.lookup({

from: 'PRODUCT_LIST',

localField: 'code',

foreignField: 'type',

as: 'productList',

})

.end()

.then(res => console.log(res))

.catch(err => console.error(err))

无法使用
