Why mongo db response value before update

Question

I need to update collection and return updated value. My code is:

const someFunction = async () => {
  const { value } = await dataStore.customerSettings.findOneAndUpdate(
            { organizationId }, 
            { $push: { archivedSuppliers: archivedSupplier } }
          );
  return value;
}

Problem is that the value is equal to collection object before update. Why is it? And how to get updated value?

Does this answer your question?

http://mongodb.github.io/node-mongodb-native/4.0/interfaces/findandmodifyoptions.html#returnoriginal

findOneAndUpdate(filter, update, options, callback)

pass option

returnOriginal: false

When false, returns the updated document rather than the original. The default is true.

await dataStore.customerSettings.findOneAndUpdate(
            { organizationId }, 
            { $push: { archivedSuppliers: archivedSupplier } },
            { returnOriginal: false } // add here
);
