我有一个安装了@ angular / fire的angular项目。我可以用Facebook登录，但是当我尝试从消息中获取令牌时，它给我一个错误
FirebaseError: Messaging: We are unable to register the default service worker. Failed to register a ServiceWorker for scope ('https://localhost:5000/firebase-cloud-messaging-push-scope') with script ('https://localhost:5000/firebase-messaging-sw.js'): An unknown error occurred when fetching the script. (messaging/failed-service-worker-registration).
我的项目设置为firebase-messaging-sw.js location，angular.json firebase-messaging-sw.js file
我不知道可能是什么问题
对不起，我的英语， 谢谢
