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

    public function getHeaderKeys(ResourceObject $ro): array
    {
        return isset($ro->headers[Header::SURROGATE_KEY]) ? explode(' ', $ro->headers[Header::SURROGATE_KEY]) : [];

The expression return IssetNode ? explode(' ', $ro->headers[BEAR\QueryRepository\Header::SURROGATE_KEY]) : array() returns the type array|string[] which is incompatible with the documented return type BEAR\QueryRepository\list.

    }
