参数2传递给Symfony \ Component \ HttpFoundation \ Cookie :: __ construct()必须是string或null类型,给出数组

I have updated my laravel version from 5.5 to 5.6 and followed the update guide but there is one error that I cannot figure out.

Error

Argument 2 passed to Symfony\Component\HttpFoundation\Cookie::__construct() must be of the type string or null, array given

My code generating this error:

public function show($id, DealService $dealService, CookieJar $cookieJar)
    {
        if(null != $coupon = $dealService->getActiveDealById($id))
        {
            if(!Cookie::has('recent'))
            {
                $ids = [];
                array_unshift($ids, $id);
                $cookieJar->queue('recent', $ids);
            }
            else
            {
                $ids = Cookie::get('recent');
                if(!in_array($id, $ids))
                {
                    array_unshift($ids, $id);
                    $ids[] = $id;
                    $cookieJar->queue('recent', $ids);
                }
            }
            if(!empty($ids))
            {
                $recent_deals = $dealService->getDealsByIds($ids);
            }
            $related_deals = $dealService->getRelatedActiveDeals($id);

            return view('couponia.show', ['coupon' => $coupon, 'recent_deals' => $recent_deals, 'related_deals' => $related_deals]);
        }
        else
        {
            return view('errors.404');
        }
    }

CookieJar queue method throws the exception as it is trying to create a Cookie instance, but this code used to work perfectly in 5.5 and the CookieJar documentation also suggests that it accepts array as argument.
