Apollo client fetchMore not updating data cache? - reactjs

Question

I am try to use #apollo/client in my nextjs application (only frontend). My backend is done using nestjs-graphql. I am facing one problem using #apollo/client.
Here is my code-
client.ts
//Initialize apolloClient
let apolloClient: ApolloClient<NormalizedCacheObject>;
//Creating link
function createIsomorphLink() {
return new HttpLink({
uri: "http://localhost:5000/piechat",
credentials: 'same-origin'
})
}
//Create apollo client
function createApolloClient() {
return new ApolloClient({
ssrMode: true,
link: createIsomorphLink(),
cache: new InMemoryCache()
})
}
//Initialize Apollo
export function initializeApollo(initialState = null) {
const _apolloClient = apolloClient ?? createApolloClient()
if (initialState) {
const existingCache = _apolloClient.extract()
const data = merge(initialState, existingCache)
_apolloClient.cache.restore(data)
}
if (!apolloClient) apolloClient = _apolloClient
return _apolloClient
}
//Use Apollo
export function useApollo(initialState = null) {
const store = useMemo(() => initializeApollo(initialState), [initialState])
return store
}
Then in nextjs getServerSideProps-
export const getServerSideProps: GetServerSideProps = async (ctx) => {
const apolloClient = initializeApollo()
await apolloClient.query({
query: GET_CONVERSATION_LIST,
context: { headers: { authorization: `Bearer ${ctx.req.cookies["session"]}` } },
errorPolicy: "all"
})
return {
props: {
initialApolloState: apolloClient.cache.extract(),
}
}
}
Then in one conversation.tsx(I use this data)-
const { data } = useQuery<GetConversationData>(GET_CONVERSATION_LIST);
On the other component (createConver.tsx) I use fetchMore function-
const { fetchMore } = useQuery(GET_CONVERSATION_LIST)
useEffect(() => {
if (data) { //If new data creation is success
fetchMore({
context: { headers: { authorization: `Bearer ${getCookie("session")}` } }, updateQuery(_, { fetchMoreResult }) {
return fetchMoreResult
}
})
}
}, [data])
Everything is well. But when I refresh my page, I see that new data not comes. please see this gif-
But I am not understanding what is the problem. I am not getting any docs or any things else. Please help me anyone.
