Mongoose 不会产生结果，但 mongo shell 会

Question

I have schema for products and it has a field storeZones object in it defined as

...
storeZones: {
  type: {
    masterZone: {type: Schema.Types.ObjectId, model: 'Zone', index: 1 },
    zone: { type: Schema.Types.ObjectId, model: 'Zone', index: 1 },
    subZone: { type: Schema.Types.ObjectId, model: 'Zone', index: 1 },
    },
    default: {
      masterZone: null,
      zone: null,
      subZone: null,
    },
  },
...

I am counting for products in a specific masterZone . So my query is

const condition = { 'storeZones.masterZone': masterZone };

console.log(condition); // { 'storeZones.masterZone': '60533e6a745d465ab6cb3fc9' }

const total = await Product.count(condition);

This returns 0 results. But when i paste the exact query in mongo shell; Robo3t to be exact.

db.products.find({'storeZones.masterZone': ObjectId('60533e6a745d465ab6cb3fc9') } )

It produces the desired output. Can someone please provide some assistance?

Fixed it by converting the masterZone from request to an ObjectId . Idk why i needed to do this, but that fixed it. so...

  const m = mongoose.Types.ObjectId(masterZone);
  const condition = { 'storeZones.masterZone': m };
  console.log(condition); // { 'storeZones.masterZone': '60533e6a745d465ab6cb3fc9'}
  const total = await Product.count(condition);
