After PHP artisan migrate : Illegal offset type in isset or empty

I get this error after I have installed the code and enter the page :

ErrorException
Illegal offset type in isset or empty (View: modules\Location\Views\frontend\blocks\list-locations\loop.blade.php)

The line that its shows the error on is:

Illuminate\Foundation\Bootstrap\HandleExceptions::handleError modules\Location\Models\Location.php:62

Code:

public function getDisplayNumberServiceInLocation($service_type)
{
    $allServices = get_bookable_services();

    if (empty($allServices[$service_type])) 
        return false;

    $module = new $allServices[$service_type];

    return $module->getNumberServiceInLocation($this);
}

::require modules/Location/Views/frontend/blocks/list-locations/loop.blade.php:7

Code:

$translation = $row->translateOrOrigin(app()->getLocale());

$link_location = false;

if (is_string($service_type)) {
    $link_location = $row->getLinkForPageSearch($service_type);
}

I can't find any solution for the error.

Instead of using empty() you can use !isset() function. Your code should be:

   public function getDisplayNumberServiceInLocation($service_type)

        {

            $allServices = get_bookable_services();

            if(!isset($allServices[$service_type])) return false;

            $module = new $allServices[$service_type];

            return $module->getNumberServiceInLocation($this);

        }
