Hey 👋 I’m going through the

<http://howtographql.com/react-apollo|howtographql.com/react-apollo>

tutorial and I got blocked by an error at the

More mutations and updating the store state

section. Can someone help me with this?

_updateCacheAfterVote = (store, createVote, linkId) => {
  // 1
  const data = store.readQuery({ query: FEED_QUERY })

  // 2
  const votedLink = data.feed.links.find(link => link.id === linkId)
  votedLink.votes = createVote.link.votes

  // 3
  store.writeQuery({ query: FEED_QUERY, data })
}

at

store.readQuery({ query: FEED_QUERY })

i get the following error:

index.js:2178 Error: Can't find field feed({"first":100,"skip":0,"orderBy":null}) on object (ROOT_QUERY) {
  "feed({\"first\":null,\"skip\":null,\"orderBy\":null})": {
    "type": "id",
    "id": "$ROOT_QUERY.feed({\"first\":null,\"skip\":null,\"orderBy\":null})",
    "generated": true
  }
}.

I’ve been around the web to find a solution for this problem, but none of them helped me. 😞 Thanks in advance for your help!

hi, you need to remove your query arguments in FEED_QUERY

@QuCode i’ll try it out in a minute

I created a pull request (https://github.com/howtographql/howtographql/pull/428) to fix that, but it still needs to be merged @nikolasburk

@QuCode thank you, it did the trick 🙏

Just merged the PR, sorry for the delay and thanks so much for catching this @QuCode! 🙏
