Wrong download file name

[MagePsycho]

I have this code in Symfony for downloading the files as a zip:

<?php
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\StreamedResponse;
use ZipStream\ZipStream;

# This class doesn't exist at all (latest version)
#use ZipStream\Option\Archive;

class FileController extends AbstractController
{
    public function download()
    {
        $zipName = 'dummy.zip';
        return new StreamedResponse(function () use ($zipName) {
            
            // Class doesn't exist at all
            /*$options = new Archive();
            $options->setContentType('application/octet-stream');
            $options->setZeroHeader(true);
            $options->setFlushOutput(true);
            $options->setSendHttpHeaders(true);*/
            
            $zip = new ZipStream($zipName);
            $zip->addFile('hello.txt', 'this is message for hello.txt');
            $zip->finish();
        });
    }
}

But when I try to download, it always dumps download file without any extension.

FYI, I using Symfony 6.2, PHP 8.1 and ZipStream 3.0

@MagePsycho You’ll have to set the correct filename using the outputName named argument. With the code above, not the name but the comment is set.
