db.collection.find限制返回字段

Question

我有以下代码，我正在尝试将返回限制为只有contractAddress，但它返回所有字段。任何人都知道我做错了什么？

  router.get('/findAddressByInterest/:interest', wrapAsync(async function(req) {
    return db.collection('myData').find({interests: req.params.interest}, {contractAddress: 1, _id: 0, interests: 0, brands: 0, medicalCondition: 0}).toArray()
  }))
