import API from "@aws-amplify/api";
import config from "./aws-exports";

Amplify.configure(config);
PubSub.configure(config);
API.configure(config);

my Component

  API.graphql(graphqlOperation(subscriptions.ticketModified)).subscribe({
      next: todoTicket => console.log(todoTicket)

the secret behind import right libraries

import Amplify, { API, graphqlOperation } from "aws-amplify";
import PubSub from "@aws-amplify/pubsub";


Amplify.configure(config);
PubSub.configure(config);
API.configure(config);
