Mutation request must contains all data required in list query. In other case list will not be updated

Bug

What is the current behavior?
I have query like that

query ListItems {
  listItems(limit: 9999) {
    items {
      __typename
      id
      title
      owner
      createdAt
      updatedAt
    }
    nextToken
  }
}

And mutation like that

mutation CreateItem($input: CreateItemInput!) {
  createItem(input: $input) {
    id
    title
    owner
    createdAt
    updatedAt
  }
}

CreateItemInput have required only title other params are optional.

When mutation is executed, list is not updated because of missing parameters owner, createdAt and updatedAt.

In console is warning with information about missing parameters.

Source code looks like that

compose(
  graphql(listItems, {
    options: {
      fetchPolicy: "cache-and-network"
    },
    props: props => {
      return {
        items: props.data.listItems ? props.data.listItems.items : []
      };
    }
  }),
  graphqlMutation(CreateList, listItems, "Item"),
)(ReactComponentRenderingList);

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.

It is a bug because in mutation response are all required parameters. List update works only with request and ignore data from response.

This functionality have weird behavior with offline > online client transition

1. Create item function is called when website is offline
2. Item list is not updated
3. Website goes online
4. Mutation is send to backend, list is updated with data from response.
   But when client is online whole time, data from response are not used.

Problem can be fixed when mutation is called with all parameters. In this case item is added to list immediately.

What is the expected behavior?

1. Mutation with variables is executed.
2. If mutation request contains all required parameters to list query, list will be updated immediately.
3. In all cases program must wait for response and use data from response to update list. (Like offline > online transition)

Which versions and which environment (browser, react-native, nodejs) / OS are affected by this issue? Did this work in previous versions?

Chrome 74
aws-appsync@1.7.2
aws-appsync-react@1.2.7
react-apollo@2.5.4

The same issue occurs in #349

Can anyone point me in the right direction around this? I want to get optimistic UI updates but I'm guessing the graphqlMutation isn't the way to go anymore? I've heard some talk about buildMutation but docs still suggest this?

Thanks

Any updates? I'm still having this problem
