Detected multiple renderers concurrently rendering the same context provider #119

Description

@jamesfrye420

I get the following warning when using this as hoc inside my Next.js app

My Apollo client:

import { ApolloClient, InMemoryCache } from '@apollo/client';
import { NextPageContext } from 'next';
import { withApollo } from 'next-apollo';
import { PaginatedPosts } from '../generated/graphql';

const createClient = (ctx: NextPageContext) =>
  new ApolloClient({
    uri: 'http://localhost:4000/graphql',
    headers: {
      cookie: (typeof window === 'undefined' && ctx?.req?.headers.cookie) || '',
    },
    cache: new InMemoryCache({
      typePolicies: {
        Query: {
          fields: {
            posts: {
              keyArgs: [],
              merge(existing: PaginatedPosts | undefined, incoming: PaginatedPosts): PaginatedPosts {
                return {
                  ...incoming,
                  posts: [...(existing?.posts || []), ...incoming.posts],
                };
              },
            },
          },
        },
      },
    }),
    credentials: 'include',
  });

export default withApollo(createClient);

and this is how I am using it inside my pages

import { Box, Button, Flex, Heading, Link } from '@chakra-ui/react';
import { NextPage } from 'next';
import NextLink from 'next/link';
import { useRouter } from 'next/router';
import IndexHeader from '../components/IndexHeader';
import Layout from '../components/Layout';
import PostStack from '../components/PostStack';
import { PaginatedPosts, usePostsQuery } from '../generated/graphql';
import withApollo from '../utils/withApollo';

const Index: NextPage = () => {
  const router = useRouter();
  const { data, loading, fetchMore, variables } = usePostsQuery({
    variables: {
      limit: 15,
      cursor: null,
    },
    notifyOnNetworkStatusChange: true,
  });

  const fetchMoreVar = () => ({
    variables: {
      limit: variables?.limit,
      cursor: data?.posts.posts[data?.posts.posts.length - 1]?.createdAt,
    },
  });

  return (
    <Layout>
      <IndexHeader />
      <PostStack
        data={data?.posts as PaginatedPosts | undefined}
        fetchMore={fetchMore}
        fetchMoreVar={fetchMoreVar}
        loading={loading}
        variables={variables}
      />
    </Layout>
  );
};
export default withApollo({ ssr: true })(Index);

on rendering this my console spits out the following warning

Warning: Detected multiple renderers concurrently rendering the same context provider. This is currently unsupported.

This warning only shows up in the pages in which ssr is set to true
