在Zig中解析JSON失败

我正在try 从这个页面https://ziglang.org/download/index.json获取和解析json. 我用的是Windows 11. 当我执行代码时，我得到以下错误:

error: MissingField

从错误中，我只能假设我的 struct 和我试图在其中解析的json之间存在一些差异，但我将 struct 字段与json的字段进行了比较，似乎并非如此.我也try 过将ignore_unknown_fields字段设置为真，但没有任何区别

以下是我的代码:

const std = @import("std");
const print = std.debug.print;
const Uri = std.Uri;
const Client = std.http.Client;
const Headers = std.http.Headers;
const FetchOptions = std.http.Client.FetchOptions;
const Location = std.http.Client.FetchOptions.Location;
const ArenaAllocator = std.heap.ArenaAllocator;

pub fn main() !void {
    var page_allocator = ArenaAllocator.init(std.heap.page_allocator);
    defer page_allocator.deinit();
    const allocator = page_allocator.allocator();

    const uri = try Uri.parse("https://ziglang.org/download/index.json");

    var client = Client{ .allocator = allocator };
    var headers = Headers{ .allocator = allocator };
    defer headers.deinit();

    try headers.append("accept", "*/*");

    var options = FetchOptions{
        .method = .GET,
        .headers = headers,
        .location = Location{ .uri = uri },
    };
    var res = try client.fetch(allocator, options);
    defer res.deinit();

    if (res.body) |body| {
        print("body: {s}", .{body});
        const parsed = try std.json.parseFromSliceLeaky(
            ZigReleases,
            allocator,
            body,
            .{ .ignore_unknown_fields = true },
        );

        const zig_releases = parsed.master;
        print("asd {}", .{zig_releases});
    } else {
        print("Request failed\n", .{});
    }
