Yii2 lajax/yii2-translate-manager or lajax/yii2-language-picker PHP8.1 throws errors

Question

I am using lajax/yii2-translate-manager and lajax/yii2-language-picker After server upgrade to PHP version 8.1 switching to another language throws an error

An Error occurred while handling another error:
ValueError: setcookie(): "path" option cannot contain ",", ";", " ", "\t", "\r", "\n", 
"\013", or "\014" in /app/vendor/yiisoft/yii2/web/Response.php:404

Previous exception:

I see that there is some cookie issue but dont know what causes this and how to fix this. Maby someone have atleast idea what to look for?

I found solution - there is new approach how to set language cookie in Yii2 newest version. In frontend(or backend - where you are using Yii2 lajax/yii2-translate-manager) -> components -> LanguageSelector.php need to rewrite code

    class LanguageSelector implements BootstrapInterface
{
    public $supportedLanguages = [];

    /**
     * @param Application $app
     */
    public function bootstrap($app)
    {
        // ignore lang parameter if language picker has been selected
        if (!empty($app->request->get('language-picker-language'))) {
            $languageCookie = new Cookie([
                'name' => 'language',
                'value' => $app->request->get('language-picker-language'),
                'expire' => strtotime('+30 days'),
                'path' => '/',
                'secure' => true,
                'sameSite' => 'None', //Select: Lax, None or Strict
            ]);
            $app->response->cookies->add($languageCookie);
            return;
        }

        // get language from request
        $preferredLanguage = $app->request->get('lang');

        if (strlen($preferredLanguage) === 2) {
            $preferredLanguage .= '-' . strtoupper($preferredLanguage);
        }

        if (!empty($preferredLanguage)) {
            $languageCookie = new Cookie([
                'name' => 'language',
                'value' => $preferredLanguage,
                'expire' => strtotime('+30 days'),
                'path' => '/',
                'secure' => true,
                'sameSite' => 'None', ////Select: Lax, None or Strict
            ]);
            $app->response->cookies->add($languageCookie);
        }

        // get language from cookie
        if (empty($preferredLanguage)) {
            $preferredLanguage = isset($app->request->cookies['language']) ? $app->request->cookies['language']->value : null;
        }

        // get language from browser
        if (empty($preferredLanguage)) {
            $preferredLanguage = $app->request->getPreferredLanguage(array_keys(Language::getLanguageNames(true)));
        }

        $app->language = $preferredLanguage;
    }
}
