Description

The following code:

<?php
$image = imagecreatetruecolor(180, 30);

try {
    var_dump(imagefilter($image, -1));
} catch (Throwable $e) {
    echo $e::class, ': ', $e->getMessage(), "\n";
}

Resulted in this output:

Fatal error: imagefilter(): Return value must be of type bool, null returned in Unknown on line 0

But I expected this output instead:

ValueError: imagefilter(): Argument #2 ($filter) must be a valid filter

Found by just staring at the code when double-checking #20066
