"Shop context types other than "single shop" are not supported"

[kierweb]

I built a payment module for Prestashop, and it was working fine in v1.7.6.x   ...  but since trying it in v1.7.7.7 I keep getting the following error when trying to Validate the order.  Any ideas?

PHP Fatal error:  Uncaught PrestaShopBundle\Exception\NotImplementedException: Shop context types other than "single shop" are not supported

        $shop = Context::getContext()->shop;
        if (!Validate::isLoadedObject($shop)) {
            $shop = new Shop((int) Configuration::get('PS_SHOP_DEFAULT'));
        }
        //Important to setContext
        Shop::setContext($shop::CONTEXT_SHOP, $shop->id);
        $this->context->shop = $shop;
        $this->context->cookie->id_shop = $shop->id;

Just before calling $module->validateOrder() method, place the code above.
