The type Koriym\AppStateDiagram\list was not found. Maybe you did not declare it correctly or list all dependencies?

    private $links;

    /** @param list<stdClass>|stdClass|null $link */
    public function __construct($link = null)
    {
        if ($link === null) {
            $this->links = [];

It seems like array() of type array is incompatible with the declared type Koriym\AppStateDiagram\list of property $links.

            return;
        }

        if (is_array($link)) {

The condition is_array($link) is always false.

            $this->links = $this->createLinkRelations($link);

            return;
        }

        $this->links = [new LinkRelation($link)];
    }

    /**
     * @param list<stdClass> $links
     *
     * @return list<LinkRelation>
     */
    private function createLinkRelations(array $links): array
    {
        $linkRelations = [];
        foreach ($links as $link) {
            $linkRelations[] = new LinkRelation($link);
        }

        usort($linkRelations, static function (LinkRelation $a, LinkRelation $b): int {
            return strtoupper($a->rel) <=> strtoupper($b->rel);
        });

        return $linkRelations;
    }

    public function __toString(): string
    {
        return implode(PHP_EOL, $this->links);

$this->links of type Koriym\AppStateDiagram\list is incompatible with the type array expected by parameter $pieces of implode().

    }
