Realm returning proxy object when realm.objects is called

I am using realm 2.1.1, react-native 0.51.0 and running debug code on Android emulator. Issue is that when I do let item = realm.objects('mySchema') proxy object is returned. Please note that I filter after. I can get array object by using itemArray = Array.from(item) but I have failed to update object within the write transaction. When I do so nothing happens

  realm.write(() => {
       itemArray[0] = newItem 
       //new item is object created using a class 
       //with the constrator. It works well in 
       //realm.create()
  });

Version of Realm and Tooling

• Realm JS SDK Version: 2.1.1
• Node or React Native: 6.11.4 or 0.51.0
• Client OS & Version: Windows 10

filtered returns a collection of objects matching the given predicate. Your code snippets attempt to use that collection as though it’s a single object, which won’t work. You need to retrieve the relevant object from the collection in order to update it.

Thanks for the response. It’s true I create the realm objects using Realm.create as specified in the docs. Say for example

//code sample_1
realm.write(() => {
  realm.create('Person', {
    name: 'Joe',
    // nested objects are created recursively
    car: {make: 'Honda', model: 'Accord', drive: 'awd'},
  });
});

Say I want to change the make of Joe’s car. I query the database to give me a Joe object as follows

//code sample_2 let Joe = realm.objects('Person').filtered('name= "Joe"');

And then I can update Joe’s car make by

//code sample_3
realm.write(() => {
  Joe.car.make= 'Isuzu';
});

My challenge is, code sample_2 returns a proxy object, and therefore I cannot run code sample_3 as it is given in that example.

One more thing you should note, is that this is the second project where I am using Realm db, with the first one everything worked as expected, as stipulated in the docs. The Realm version was 2.0.3.

This second one with Realm 2.1.1 has got me scratching my head. Any help will highly be appreciated.
