I'm getting a hard time adding an object to an array inside a JSON object.
This is my state:

```
const DATA = 
{

 data: [

{
  id: 1,
  routeName: 'my 2 route',
  origin: 'Tel Aviv',
  destination: 'Netanya',
  date: '25-01-2021',
  km: '60',
  stops: [
    {
      id: 0,
      address: 'test',
      lat: '32.0853',
      lon: '34.7818',
      customerName: 'test',
      tel: '00000',
    },
    {
      id: 1,
      address: 'adddress',
      lat: '32.0853',
      lon: '34.7818',
      customerName: 'test',
      tel: '00000',

    }
  ],
},
{
  id: 2,
  routeName: 'my second route',
  origin: 'Holon',
  destination: 'Hadera',
  date: '12-02-2021',
  km: '70',
  stops: [
    {
      id: 0,
      address: 'address0',
      lat: '32.0853',
      lon: '34.7818',
      customerName: 'customer0',
      tel: '00000000',
    },
    {
      id: 1,
      address: 'address1',
      lat: '32.0853',
      lon: '34.7818',
      customerName: 'customer1',
      tel: '00000000',
    },
  ],
},

 ],
}

```

I don't know how to write the reducer, tried few ways but the state doesn't change.
My reducer gets the route id + stop to add this route.
I will be happy for some help here :)
