Cannot read property 'subscribeToMore' of undefined

Hi,

When I try to subscribe on updates like this:

this.data = this.apollo
  .watchQuery({
    query: controllersListQuery,
    variables: {
      accountId: this.accountId,
      status: this.status,
      oemId: this.oemId,
      search: this.search,
    },
  });

this.data.subscribeToMore({
  document: gql`
    subscription OnCreateController($accountId: ID!) {
      controllerCreated(accountId: $accountId) {
        id
      }
    }
  `,
  variables: {
    accountId: '896ae9dd-7aed-4e5f-88d7-e93acd331f0c',
  },
  updateQuery: (previousResult, { subscriptionData, variables }) => {
    console.log(previousResult, subscriptionData, variables);
    return previousResult;
  },
  onError: (err) => console.error(err),
});

I get an error: Cannot read property 'subscribeToMore' of undefined. As I see at some point in this place getRef() returns object without ref:

private getObservableQuery(): ObservableQuery<T> {
  if (this.apollo instanceof ObservableQueryRef) {
    const ref = this.apollo as ObservableQueryRef;
    return ref.getRef();
  }

  return this.apollo as ObservableQuery<T>;
}

and when it tries to subscribeToMore() here:

public subscribeToMore(options: any): () => void {
  return this.getObservableQuery().subscribeToMore(options);
}

ref is undefined.

Thanks in advance for any help and big thanks for your work on this package!

So from feb there is no one from the developers which can say how to use SubscribeToMore correct ?

If you use apollo-angular then we changed the way ApolloClient works with RxJS. You can check it here: kamilkisiela/apollo-angular#377

No more this kind of issues.
