Hi everyone , I wish you are fine ...  
I'm trying to connect my neo4j database with flutter application , after searching here I found that grandstack is the solution .  
So I am using graphql\_flutter but I have some exceptions that I can't fixed it , as shown in the screenshot

- I use Windows 10 OS , with neo4j desktop version  
I use Graphql Architect to connect with Flutter application

Could you please share the `GraphQLClient` code that you're using? Also, is the server working as expected? Did you connect successfully to the playground and return the data as expected?

Here's an example of the `GraphQLClient` code that I'm talking about.

```nohighlight
const clientUri = 'http://ip-adress-here:4001/graphql';

GraphQLClient getClient({String? subscriptionUri, required String tokenId}) {

    Link link = HttpLink(
      clientUri,
      defaultHeaders: {
        'Authorization': '''Bearer $tokenId''',
      },
    );

    if (subscriptionUri != null) {
      final WebSocketLink websocketLink = WebSocketLink(
        subscriptionUri,
        config: const SocketClientConfig(
          autoReconnect: true,
          inactivityTimeout: Duration(seconds: 30),
        ),
      );

      link = link.concat(websocketLink);
    }

    return GraphQLClient(
      cache: cache,
      link: link,
    );
  }

```
