System.Text.Json.JsonException: "The JSON value could not be converted to ConsoleApp3.Data. Path: $ : LineNumber: 0 : BytePositionInLine: 1."

I inserted a reference to the api-https://api.vimeworld.ru/user/name/" + nickname, and the program swears that you can't transform string into System.Text.Json.JsonSerializerOptions, if the brackets leave empty, it's "Jolet.Jusson value." Path: $ : LineNumber: 0 : BytePositionInLine: 1."

Class Data

public class Data
    {
        public int id { get; set; }
        public string username { get; set; }
        public int level { get; set; }
        public float levelPercentage { get; set; }
        public string rank { get; set; }
        public int playedSeconds { get; set; }
        public int lastSeen { get; set; }
        public Guild guild { get; set; }
    }

Code

class Program
    {
        private static readonly HttpClient client = new HttpClient() { DefaultRequestVersion = HttpVersion.Version20 };
    static async Task Main(string[] args)
    {
        
        string nickname = Console.ReadLine();
        string requesUri = "https://api.vimeworld.ru/user/name/" + nickname;
        
        using HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, requesUri);
        using HttpResponseMessage response = await client.SendAsync(request, HttpCompletionOption.ResponseHeadersRead);
        Data result = await response.Content.ReadFromJsonAsync<Data>();
        int id = result.id;

        Console.ReadKey();

JSON contains a mass []Not the object {}♪

The private case of a single-element solution would look like that.

Data result = (await response.Content.ReadFromJsonAsync<Data[]>())[0];
