updateQuery: (previous, { subscriptionData }) => {
              console.log(subscriptionData)
              console.log(previous, subscriptionData)
              const newAllLinks = [
                subscriptionData.data.newLink.node,
                ...previous.feed.links
              ]
              const result = {
                ...previous,
                feed: {
                  links: newAllLinks
                }
              }
              return result
            }

I keep getting:

errorHandling.js?ace3:7 TypeError: Cannot read property 'node' of null

is this a web app? Then you can inspect the WS Frames to investigate the response from the server

I found the issue. I am using apollo boost which does not currently support ws connection. Had to remove it and did things the usual way of importing tons of libraries lol

oh wow ok! Didn't know that thanks
