Accessing nested json data with Hooks

I am having trouble filtering the json that I have in React Typescript Using Hooks. I have a JSON that comes from a fetch and it looks like this:

[
{
"dealer 1":
    [
    {
    "name": "SERVICE 1"
    "city": "NORTH CANTON"
    "phone": "3306596372"
    "isOpen": "true"
    },
    {
    "name": "SERVICE 2"
    "city": "OHIO"
    "phone": "3306596372"
    "isOpen": "true"
    }
    ]
},
{
"dealer 2":
    [
    {
    "name": "SERVICE A"
    "city": "WASHINGTON"
    "phone": "3306596375"
    "isOpen": "true"
    },
    {
    "name": "SERVICE B"
    "city": "SEATTLE"
    "phone": "3306596376"
    "isOpen": "true"
    }
    ]
}
]

my code for fetching the api is:

useEffect(() => {
    axios.get("API URL here")
        .then(res => {
            console.log(res)
            setCTSN(res.data)
        });
}, []);

and I wanted to return all open dealers so I need to filter it by "isOpen=true"

const isOpen = 'true'

const result = OPEN
    .map(item => ({
        ...item, //Spread types may only be created from object types.ts(2698)
        children: item.children
            .filter(child => child.value.includes(isOpen.toLowerCase()))
    }))
    .filter(item => item.children.length > 0)

console.log(result)

but I am getting an error with the '...item' and I'm not sure if I am doing it correctly in React Typescript.

Can someone help me?

You should make ur OPEN array with this method then use map for showing them on react.

if u have trouble with showing them , ask me for code on comment.

const Json = [
  {
    "dealer 1": [
      {
        "name": "SERVICE 1",
        "city": "NORTH CANTON",
        "phone": "3306596372",
        "isOpen": true
      },
      {
        "name": "SERVICE 2",
        "city": "OHIO",
        "phone": "3306596372",
        "isOpen": false
      }
    ]
  },
  {
    "dealer 2": [
      {
        "name": "SERVICE A",
        "city": "WASHINGTON",
        "phone": "3306596375",
        "isOpen": true
      },
      {
        "name": "SERVICE B",
        "city": "SEATTLE",
        "phone": "3306596376",
        "isOpen": true
      }
    ]
  }
]
const OPEN = []
Json.forEach(item => {
   OPEN.push({
      dealer:Object.keys(item)[0],
      service:item[Object.keys(item)[0]].filter(service =>service.isOpen)
   })
})
console.log(OPEN)

You can do it this way

OPEN.filter(item => item[Object.keys(item)[0]].some(service => service.isOpen))

But IMHO you have a problem with the json data, it doesn't looks like a good modelling.

This structure would be better, and thus filtering easier:

{
name: "dealer 1",
services:
    [
    {
    "name": "SERVICE 1"
    "city": "NORTH CANTON"
    "phone": "3306596372"
    "isOpen": "true"
    },
    {
    "name": "SERVICE 2"
    "city": "OHIO"
    "phone": "3306596372"
    "isOpen": "true"
    }
    ]
}

and then filter like this...

OPEN.filter(item => item.services.some(service => service.isOpen))
