How to remove Task json properties in Nancy.Response.AsJson - json

Question

I've made one of my API endpoints and inner logic asynchronous and when previously I've used Response.AsJson(Foo.bar()) , it would return the json representation normally, but now I see this appended to it:
{
"result": [
{
"id": "59d680cc734d1d08b4e6c89c",
"properties": {
"name": "value"
}
}
],
"id": 3,
"exception": null,
"status": 5,
"isCanceled": false,
"isCompleted": true,
"isCompletedSuccessfully": true,
"creationOptions": 0,
"asyncState": null,
"isFaulted": false
}
But I want it to be like this:
"id": "59d680cc734d1d08b4e6c89c",
"properties": {
"name": "value"
}
As I understand, it's because I've wrapped my object in a Task , but I can't figure out, how with Nancy framework, which I use the Response.AsJson, to make it so the properties are excluded. I can obviously omit the Response.AsJson of the returned object, but then response is no longer Json if requesting through web-browser for example.
For further example
NancyModule for routing API:
public ItemCatalogModule(IItemCatalog itemCatalog) : base("/itemCatalog")
{
Get("/fetch/{id}", async parameters =>
{
var id = (string) parameters.id;
var response = await Response.AsJson(itemCatalog.GetItem(id));
return response;
});
}
How the interface looks like of ItemCatalog:
public interface IItemCatalog
{
Task<Item> GetItem(string id);
}

You shoud do this :
public ItemCatalogModule(IItemCatalog itemCatalog) : base("/itemCatalog")
{
Get("/fetch/{id}", async parameters =>
{
var id = (string) parameters.id;
return Response.AsJson(await itemCatalog.GetItem(id));
});
}
