The variable $matches seems only to be defined at a later point. Did you maybe move this code here without moving the variable definition?

                   $domain = $matches[1];

                }

                if ($result->success && (!config('recaptcha.verify_domain') || $domain_verified)) {
                    return $next($request);
                }
            }
        }
        
        // Emit an event and return to the previous view with an error (only the captcha error will be shown!)
        event(new FailedCaptcha($request->ip(), $response_domain));
        return back()->withErrors(['g-recaptcha-response' => trans('strings.captcha_invalid')])->withInput();
    }
