Help what is the problem
const FormData = require(form-data)
const fetch = require(node-fetch)
const path = require("path")
const basePath = process.cwd();
const fs = require("fs");

fs.readdirSync(`${basePath}/build/images`).
forEach(file => {
const formData = new FormData();
const fileStream = fs.createReadStream(`${basePath}/build/images/${file}`);
formData.append("file", fileStream);

let url = '';

let options = {
method: "POST",
headers: {
Authorization: '',
},
body: formData
};

fetch(url, options)
.then((res) => res.json())
.then((json) => {
const filename = path.parse(json.file_name).name;
let rawdata = fs.readFileSync(`${basePath}/ build/json/${filename}.json`)
let metadata = JSON.parse(rawdata);

metadata.file_url = json.ipfs_url

fs.writeFileSync(`{basePath}/build/json/${filename}.json`, JSON.stringify(metadata, null, 2));

console.log(`${json.file_name} uploaded & ${filename}.jsonupdated!`);
