BUG PNG to WEBP conversion

Hello,
I have a small problem when converting PNG to WEBP, when an empty file is
created.
My code is
$image = Image::fromString( $fileContents, $type );
$image->resize(800, null);
dump($image->toString($image->getWidth()); //Prints the value 800
dump($image->toString(Image::WEBP, 85)); // Prints the value ''
Uploading PNG image with size 800×600, 196 kB
But if I change $image->resize(801, null); or $image->resize(799, null); then everything works as it should. Yes, I can fix it this way using IF which I will obviously have to do but it seems like a BUG to me.

Hello @Vred,
Image::toString does not expect int 800 as parameter.
Image::toString(int $type = ImageType::JPEG, ?int $quality = null): string
I tried this and it works as expected.
$image = Image::fromFile(__DIR__ . "/img.PNG", $type); // $type = 3 = IMAGETYPE_PNG
//$image->getWidth(); = 232
$image->resize(800, null);
//$image->getWidth(); = 800
$this->sendResponse(new CallbackResponse(function() use($image) {
$this->getHttpResponse()->addHeader("Content-type", "image/webp");
echo $image->toString(Image::WEBP, 85);
}));
Different image works?
