WP_Error if cannot reach external URL

Suggestion to fix Fatal “Cannot use object of type WP_Error as array”.

            $response = wp_remote_get($rest_api_url);
            if (is_array($response) && !empty($response['response']['code'])) {
                if ($response['response']['code'] == 200) {
                    $products = json_decode($response['body'], true);
                }
            } else {
                return false; // wp_remote_get failed somehow
            }

Otherwise the plugin will break the page when the remote URL is not returning any response or in my case when I worked on a local server and had no wifi for some time.
