3 years ago There is something wrong with your zip file.
I use curl -o corrupted.zip https://github.com/ZJONSSON/node-unzipper/files/5149151/corrupted.zip
And this code
const fs = require("fs");
const unzip = require("unzipper");
let inStream = fs.createReadStream("./corrupted.zip");`
inStream.on("open", ()=> {
inStream.pipe(unzip.Parse()).on("entry", (entry) => console.log(entry.path));
});
I get result: invalid signature: 0x6d74683c
I recompressed your image file into mine.zip and ran the code again:
const fs = require("fs");
const unzip = require("unzipper");
let inStream = fs.createReadStream("./mine.zip");`
inStream.on("open", ()=> {
inStream.pipe(unzip.Parse()).on("entry", (entry) => console.log(entry.path));
});
I get result: b7c4d01c3200558d594134f3a320c5.jpeg

I am using this library to Parse a stream and extract from zip on the fly without storing the whole zip locally (stream to my server parse and send on entry to another server). I uploaded a zip with 250k images it fails on 'end of file Zlib zlibOnError 5 Z_BUF_ERROR' at the exact same entry every time, I removed this file and the parse works fine, I created a new zip with only that file and it fails every time (Using parse - for my code I must use parse since I don't store the whole file). I attached this file to the issue so you can check and see if there is a way to overcome this issue and perhaps skip it in flow, I tried to autodrain this specific entry but it mess up the next entry signature. p.s. I can open the file and view the image and also both in ubuntu and windows I can extract the file from the zip with no problem, the issue occurs only when I try to parse it from stream.
