Form Update to v3.0.2 causing Form::getAction() error, maybe?

Return value of Grav\Plugin\Form\Form::getAction() must be of the type string, null returned

    public function getAction(): string
    return $this->items['action'] ?? $this->page;


I recently updated my Grav plugins, including the Form plugin and I’m now receiving this error when trying to load a page with a Form on it. I’m really at a loss to what it could be, as It’s been a fully functional form till now. Any guidance out there? Thanks in advance!
