I tried finding type of file using file-type module but when i try to run it gives me error that error:.... fileType.fromBuffer is not a function.

`

const fileType = require('file-type');

const readChunk = require('read-chunk');

exports.ext = async function(file) {

const buffer = readChunk.sync(file, 0, 512)

let type = await fileType.fromBuffer(buffer);

console.log(type of file,type)

return value

`

this is in utils.js file and i am calling it in other type.js file

`

var extension =  await utils.ext('ABC.png')

 console.log(extension)

`

Can anybody tell me what should i do?
