错误：调用 `server.applyMiddleware()` 之前必须 `await server.start()`

更新后apollo-server到版本 3 控制台中显示以下错误

C:\projects\my_project\node_modules\apollo-server-core\src\ApolloServer.ts:554

Adding server.start() before server.applyMiddleware()并不能解决问题。有什么建议么？

这就是对我有用的替代方案await server.start()

server.start().then(res => {
  server.applyMiddleware({ app, path: '/' });

  app.listen({ port }, () => 
    console.log(`Gateway API running at port: ${port}`)
  );  
});
