Uncaught (in promise) ApolloError: undefined - graphql-ws

[manojkumar3692]

I'm new to implementing a socket connection, Basically, I'm trying to connect to the socket from the client side using graphql ws

im getting following error

Uncaught (in promise) ApolloError: undefined

WebSocket connection to 'ws://localhost:4000/' failed:

client code :

`
import { ApolloClient, InMemoryCache, ApolloProvider } from '@apollo/client';
import { GraphQLWsLink } from "@apollo/client/link/subscriptions";
import { createClient } from "graphql-ws";

const link = new GraphQLWsLink(
createClient({
url: "ws://localhost:4000/",
}),
);
const client = new ApolloClient({
uri: 'http://localhost:4000/',
cache: new InMemoryCache(),
link,
});

`

I want ws to be connected on page load and I'm trying to push data on submit, Building a simple chat application using graphql , apollo client, and react

what is the mistake I'm doing here, is it something related to the version, etc ??

Hey there, sorry I have no idea I have practically zero Apollo experience, and that error message doesn't tell me anything.

If you can create a repro that I can run, I will be willing to take a look.
