Forge .NET API RuntimeBinderException

I'm using Forge .NET API 1.3.0

I'm trying to get hubs via API, just like it is described in the example

I know that...

But for some reason the following line fails with RuntimeBinderException:

Hubs hubs = apiInstance.GetHubs(/*filterId, filterExtensionType*/);

The exception message says:

Exception thrown: 'Microsoft.CSharp.RuntimeBinder.RuntimeBinderException' in Unknown Module. Additional information: Cannot implicitly convert type 'Autodesk.Forge.Model.DynamicJsonResponse' to 'Autodesk.Forge.Model.Hubs'

So obviously the method example shows is not valid anymore (?). How should the resulting data to be converted into Hubs type.

This happened to me as well. I solved it using Json Deserializer.

        string token = "a token";
        var apiInstance = new HubsApi();
        apiInstance.Configuration.AccessToken = token;

        // Get Hub
        dynamic hubsJson = apiInstance.GetHubs();
        Hubs allHubs = JsonConvert.DeserializeObject<Hubs>(hubsJson.ToString());

Now the json object is converted to the Forge Api Hubs class.

OK, I managed to get it working by using the raw data. Following an example:

var hubs = await hubsApi.GetHubsAsync();
foreach (KeyValuePair<string, dynamic> hubInfo in new DynamicDictionaryItems(hubs.data))
{
  new { Id = hubInfo.Value.id, Name = hubInfo.Value.attributes.name }
}

For a reference, following kind of data is inside the "hubs.data" array:

{
"type": "hubs",
"id": "b.aaaaaaaa-bbbb-cccc-1111-222223333333",
"attributes": {
    "name": "The hub",
    "extension": {
        "type": "hubs:autodesk.bim360:Account",
        "version": "1.0",
        "schema": {
            "href": "https://developer.api.autodesk.com/schema/v1/versions/hubs:autodesk.bim360:Account-1.0"
        },
        "data": {}
    }
},
"links": {
    "self": {
        "href": "https://developer.api.autodesk.com/project/v1/hubs/b.aaaaaaaa-bbbb-cccc-1111-222223333333"
    }
},
"relationships": {
    "projects": {
        "links": {
            "related": {
                "href": "https://developer.api.autodesk.com/project/v1/hubs/b.aaaaaaaa-bbbb-cccc-1111-222223333333/projects"
            }
        }
    }
}

}

The .NET tutorial shows how to list hubs, you can also download the ready-to-use sample, the DataManagementController code shows it in action, see here.
