        }

        $value = substr($this->token->getValue(), ...$params);

$params is expanded, but the parameter $offset of substr() does not expect variable arguments.

The property token does not exist on nicoSWD\Rule\Grammar\JavaScript\Methods\Substr. Did you maybe forget to declare it?

        return new TokenString((string) $value);
    }
