glebdmitriew#1 (comment) I found another similar issue with a possible explanation. The zip file Im using was infact previously in another zip containing it

Had the same issue, what worked for me was switching my code over to use one of the Open methods instead

I'm just trying unzipped out and getting this error. My zips come from Macs and contain around 20 files and are about 20Mb in size. Tried two different zips with the same results using:

        const zip = fs.createReadStream(downloadedFilePath).pipe(unzipper.Parse({forceStream: true}));
        for await (const entry of zip) {
          const fileName = entry.path;
          console.debug(`File: ${fileName}`)
        }

Stack is:

Now tried using Open like this

let zip = await unzipper.Open.file(downloadedFilePath)
zip.files.forEach( (file) => {
    console.debug(`[events_pubsub.ts] handleUploadScreenshotsEvent: Validating screenshot file ${file.path}`)
})

And it gives me a whole different error:

>              ^

Unzipper does not handle 7zip files, unless someone is willing to do the work and submit a PR.
