502 Bad Gateway

[MicaelaDJ]

I tried doing this...

$frames = array("img1.jpg", "img2.jpg");
$durations = array(300);
$anim = new GifCreator\AnimGif();

$anim->create($frames);

$gif = $anim->get();
header("Content-type: image/gif");
echo $gif;
exit;

but when i try to send it to the browser I am getting a bad gateway error. my current php version is 7.3.26
