Amplify No pubsub module applied for subscription ReactJs

Question

I am facing issue with subscriptions its throw exception

No pubsub module applied for subscription

index.js

import Amplify from "@aws-amplify/core";
import PubSub from "@aws-amplify/pubsub";
import API from "@aws-amplify/api";
import config from "./aws-exports";

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

my Component

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

what I am missing?

Answer 1

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);
