Read JSON from local file but error on map function

I followed a few articles on how to read json data from a local file in React and they are recommending using map function. Like https://morioh.com/p/316b1492cfda

I am getting an error

Property 'map' does not exist on type '{ updated: number; }'.ts(223)

Here is my code

import UpdatedFile from '../public/updated.json';const[Updated,setUpdated]= useState("9/9/2020");  const newdata = UpdatedFile.map((data) =>{  // This is where the error is coming    return (      setUpdated({map.updated})    )      });

This is how my JSON file looks like.

{"updated": 1599692605913}

Any idea why its not recognizing map as a valid function?
