Grav 1.7.42 crashes in Grav\Common\Utils isDangerousFunction - strtolower

[softyde]

The following Twig expression leads to a crash in Utils.isDangerousFunction

 {% set first_image = p.media.images|filter(i => not(i.filename starts with '___'))|first %}

Grav 1.7.42

As a workaround I was able to install 1.7.41.2 via direct installation.

quick fix would be to wrap that higlighted line in a check:

if (is_string($name)) {
    $name = strtolower($name);
}
