CatAPI Json deserialization issue.

I'm having trouble getting my code to deserialize my json correctly. When I run my Program.cs I get

API Response: [{"id":"530","url":"https://cdn2.thecatapi.com/images/530.jpg","width":448,"height":538}]
Deserialized Cat URL: 
value=HereKitty.RandomCat
url=

API Response: [{"id":"530","url":"https://cdn2.thecatapi.com/images/530.jpg","width":448,"height":538}]
Deserialized Cat URL: 
value=HereKitty.RandomCat
url=

But I'm not able to access the fields in the json. My Program.cs

        var filePath = "/home/deca/auth/cat_api.json";
        using var doc = JsonDocument.Parse(File.ReadAllText(filePath));
        var apiKey = doc.RootElement.GetProperty("api_key").GetString();
        var kitty = new HereKitty(apiKey);
        
        var response = await kitty.GetRandomCatAsync();
        Console.WriteLine($"value={response}");
        Console.WriteLine($"url={response.Url}");

        var filePath = "/home/deca/auth/cat_api.json";
        using var doc = JsonDocument.Parse(File.ReadAllText(filePath));
        var apiKey = doc.RootElement.GetProperty("api_key").GetString();
        var kitty = new HereKitty(apiKey);
        
        var response = await kitty.GetRandomCatAsync();
        Console.WriteLine($"value={response}");
        Console.WriteLine($"url={response.Url}");

my Json class

public class RandomCat
{
    public string Id { get; set; }
    public string Url { get; set; }
    public int Width { get; set; }
    public int Height { get; set; } 
}

public class RandomCat
{
    public string Id { get; set; }
    public string Url { get; set; }
    public int Width { get; set; }
    public int Height { get; set; } 
}

the response

{"id":"530","url":"https://cdn2.thecatapi.com/images/530.jpg","width":448,"height":538}

{"id":"530","url":"https://cdn2.thecatapi.com/images/530.jpg","width":448,"height":538}

my function

    public async Task<RandomCat> GetRandomCatAsync()
    {
        var response = await _httpClient.GetAsync("images/search");
        response.EnsureSuccessStatusCode();
        var responseBody = await response.Content.ReadAsStringAsync();
        Console.WriteLine($"API Response: {responseBody}");
       using var jData = JsonDocument.Parse(responseBody);
        var catData = jData.RootElement[0]; // Access the first element of the JSON array

        RandomCat cat = JsonSerializer.Deserialize<RandomCat>(catData.GetRawText()); // Deserialize the first element
        Console.WriteLine($"Deserialized Cat URL: {cat?.Url}"); 
        return cat;
    }

    public async Task<RandomCat> GetRandomCatAsync()
    {
        var response = await _httpClient.GetAsync("images/search");
        response.EnsureSuccessStatusCode();
        var responseBody = await response.Content.ReadAsStringAsync();
        Console.WriteLine($"API Response: {responseBody}");
       using var jData = JsonDocument.Parse(responseBody);
        var catData = jData.RootElement[0]; // Access the first element of the JSON array

        RandomCat cat = JsonSerializer.Deserialize<RandomCat>(catData.GetRawText()); // Deserialize the first element
        Console.WriteLine($"Deserialized Cat URL: {cat?.Url}"); 
        return cat;
    }

Does anyone know what I'm doing wrong?

❔ Class method construction using lambda?

I was looking at some Avalonia code and I noticed this code internal class Database { public IEnumerable<TodoItem> Get public IEnumerable<TodoItem> GetItems() => new[] { new TodoItem{Description = "Walk the dog" }, new TodoItem{Description = "Buy some milk"}, new TodoItem{Description = "Learn Avalonia", isChecked = true } }; I'm confused about the => new[] part. If the method had just been public IEnumerable<TodoItem> GetItems() { new TodoItem{Description = "Walk the dog" }, new TodoItem{Description = "Buy some milk"}, new TodoItem{Description = "Learn Avalonia", isChecked = true } }; I wouldn't have batted an eye. Does => new[] just mean collect the results in a curly brace into an array? What is this feature called?
