Why I do not receive a real object?

I run a GraphQL client and send the queries

```
var response3 = await client2.SendQueryAsync(request2);
var response2 = await client2.SendQueryAsync(request2);
var response1 = await client2.SendQueryAsync(request2);
```
There is
```
public class ADescriptorResponse2
{
public ADescriptor aDescriptor { get; set; }
}
public class ADescriptor
{
public long Action { get; set; }
public string Name { get; set; }
public string Description { get; set; }
}

```

But in the 1st case
var response3 = await client2.SendQueryAsync(request2);
i receive the response3.Data ==null, type ADescriptorResponse2
In other both cases I receive Data correct but it isNewtonsoft.Json.Linq.JObject type.
Why I do not receive the Data of ADescriptorResponse2 filled with data?
What is incorrect?
