如何从eBay API下载和解压缩文件

我正在尝试从ebays api获取文件

我正在获取数据，但它无法正确解压缩或正确编码。它应该是一个gzip的XML文件。实际上，文档并不清楚。我正在使用RESTSHARP进行HTTP调用（106.15.0）。
例外：在解码

我的代码时发现了无效的数据：

const string url = "sell/feed/v1/task/task-16-SOMENUMBER/download_result_file";
        var restClient = new RestClient(_restApiUrl)
        {
            Authenticator = new OAuth2AuthorizationRequestHeaderAuthenticator(authentication.AuthorizationToken, "Bearer")
            
        };

        var httpRequest = new RestRequest(url, Method.GET);
        httpRequest.AddHeader("Accept-Encoding", "application/gzip");
        httpRequest.AddHeader("Accept", "*/*");
        byte[] myfile = restClient.DownloadData(httpRequest);
        var decodedString = Encoding.UTF8.GetString(myfile);
        using (var stream = new MemoryStream(myfile))
        {
            string res;
            using (GZipStream zipStream = new GZipStream(stream, CompressionMode.Decompress))
            {
                using (var sr = new StreamReader(zipStream))
                {
                    res = sr.ReadToEnd(); //ERROR HERE: Found invalid data while decoding
                }
            }
            var result = res;
        }

返回字符串的第一个30（encoding.default.getString（myfile）） pk \ u0003 \ u0004 \ u0014 \ 0 \ b \ b \ b \ b \ b \ b \ 0 \ f£†t \ t \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 \ 0 0 \ 0 ActiveInVentoryReport

I am attempting to get a file from Ebays API
https://developer.ebay.com/api-docs/sell/feed/resources/task/methods/getResultFile#h2-samples

I am getting data back but it is not decompressing properly or encoding properly. It should be an gziped xml file. The documentation is not very clear on this actually. I am using RestSharp for my http calls (106.15.0).
Exception:
Found invalid data while decoding

My Code:

const string url = "sell/feed/v1/task/task-16-SOMENUMBER/download_result_file";
        var restClient = new RestClient(_restApiUrl)
        {
            Authenticator = new OAuth2AuthorizationRequestHeaderAuthenticator(authentication.AuthorizationToken, "Bearer")
            
        };

        var httpRequest = new RestRequest(url, Method.GET);
        httpRequest.AddHeader("Accept-Encoding", "application/gzip");
        httpRequest.AddHeader("Accept", "*/*");
        byte[] myfile = restClient.DownloadData(httpRequest);
        var decodedString = Encoding.UTF8.GetString(myfile);
        using (var stream = new MemoryStream(myfile))
        {
            string res;
            using (GZipStream zipStream = new GZipStream(stream, CompressionMode.Decompress))
            {
                using (var sr = new StreamReader(zipStream))
                {
                    res = sr.ReadToEnd(); //ERROR HERE: Found invalid data while decoding
                }
            }
            var result = res;
        }

First 30 of returned string (Encoding.Default.GetString(myfile))
