Argument #1 ($progressTarget) must be of type string, null given, called in vendor/norkunas/youtube-dl-php/src/YoutubeDl.php on line 139

[schulzrinne]

I'm using the example on the home page, verbatim (with dev-master from today; no laravel).

[norkunas]

Please give your code sample how do you use it and a test link :)

[schulzrinne]

Copy-pasted from the README, verbatim:

$yt = new YoutubeDl();

$yt->onProgress(static function (string $progressTarget, string $percentage, string $size, string $speed, string $eta, ?string $totalTime): void {
    echo "Download file: $progressTarget; Percentage: $percentage; Size: $size";
    if ($speed) {
        echo "; Speed: $speed";
    }
    if ($eta) {
        echo "; ETA: $eta";
    }
    if ($totalTime !== null) {
        echo "; Downloaded in: $totalTime";
    }
});

$collection = $yt->download(
    Options::create()
        ->downloadPath('/tmp')
        ->url('https://www.youtube.com/watch?v=oDAw7vW7H0c')
);

foreach ($collection->getVideos() as $video) {
    if ($video->getError() !== null) {
        echo "Error downloading video: {$video->getError()}.";
    } else {
        echo $video->getTitle(); // Will return Phonebloks
    }
}

Works for me. please enable process debugging to check what's going on.

How do I enable process debugging? The documentation seems silent on this.

The problem seems to appear on the 2nd (and subsequent downloads). Stack trace below:
