If i try to save a document, sometimes i got this error:

It comes from:

abstract class AbstractSluggableLinkGenerator implements LinkGeneratorInterface
{
    protected function slugify($string): string
    {
        return strtolower(
            trim(
                preg_replace('~[^0-9a-z]+~i', '-', html_entity_decode(
                    preg_replace(
                        '~&([a-z]{1,2})(?:acute|cedil|circ|grave|lig|orn|ring|slash|th|tilde|uml);~i',
                        '$1',
                        htmlentities($string, ENT_QUOTES, 'UTF-8')
                    ),
                    ENT_QUOTES,
                    'UTF-8'
                )),
                '-'
            )
        );
    }
}

Hi. Same error here. When returning a random string from slugify method, the stuff works. Don't know why, but could you please fix this? Pretty please <3

Guess you use link-generators for objects that don't have a name?

[albertmueller]

that's happen also on documents, without use of objects. "fixed" it local with a return of a empty string if $string is null

[dpfaffenbauer]

It happens with documents cause of the validation check where Pimcore renders the documents thus triggering the link generator

[albertmueller]

but can we return a empty string if $string is null? otherwise it is a bit confusing if you don't know whats going on. if you agree i can do a PR?

[dpfaffenbauer]

yes, I guess that would be a solution

[dpfaffenbauer]

that has been fixed
