我發了 issue 呢，快來抗抗 >>
[useQuery fetch data is different in network and console.log](https://github.com/apollographql/apollo-client/issues/8359)

### 最終解法是在 `InMemoryCache` > `typePolicies` 加上 data 的 key 值 MsgInvite

const createApolloClient = ({ onError }) => {
  return new ApolloClient({
    link: from([authMiddleware, createErrorLink(onError), splitLink]),
    cache: new InMemoryCache({
      typePolicies: { MsgInvite: { keyFields: ['inviteeUserIDs'] } }
    })
  });
};

或是你遇到的是 refetch cache 的問題呢？
