crash on unzipper zip file

[jefripunza]

How can we reproduce the crash?

i dont know whats it is ...

code :

import fs from "fs"; import path from "path";

import express from "express"; import cors from "cors"; import helmet from "helmet"; import dotenv from "dotenv"; import morgan from "morgan"; import axios from "axios"; import unzipper from "unzipper";

const icon_urls = [ // download all icons and save to icon folder "https://phosphoricons.com/assets/phosphor-icons.zip", ];

// make icon folder, if it doesn't exist if (!fs.existsSync("./icon")) { fs.mkdirSync("./icon"); }

// delete all files in icon folder fs.readdirSync("./icon").forEach((file) => { fs.unlinkSync(path.join("./icon", file)); });

console.log("Downloading icons!"); for (const url of icon_urls) { const response = await axios.get(url, { responseType: "arraybuffer" }); const buffer = Buffer.from(response.data, "binary"); const filename = url.split("/").pop() as string; const file = await Bun.file(./icon/${filename}); const writer = await file.writer(); await writer.write(buffer);

// if file is zipped, extract it if (filename.endsWith(".zip")) { const directory = await unzipper.Open.file(./icon/${filename}); await directory.extract({ path: "./icon" }); } }

dotenv.config();

const app = express(); app.use(cors()); app.use(helmet()); app.use(morgan("dev"));

app.get("/", async (req, res) => { res.json({ message: "Hello, world!", }); });

app.listen(3000, () => { console.log("Server is running on port 3000"); });
