Custom HttpClientFactory doesnot work after upgrade to new version

I got a “Unable to read data from the transport connection” error with the follow codes, but it works with the old version.

thank you.

           var proxy = "http://192.168.1.200:8080";
            var client = new DirectoryService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = "Gbackuper Directory Helper Class",
                HttpClientFactory = new ProxyHttpClientFactory(proxy),
            });
            
           var orgunitsRequest = client.Orgunits.List("my_customer");
           orgunitsRequest.Type = OrgunitsResource.ListRequest.TypeEnum.All;
           var orgs = await orgunitsRequest.ExecuteAsync(cancellationToken);


    public class ProxyHttpClientFactory : HttpClientFactory
    {
        private string _proxyUrl;
        public ProxyHttpClientFactory(string proxyUrl)
        {
            _proxyUrl = proxyUrl;
        }
        
        protected override HttpMessageHandler CreateHandler(CreateHttpClientArgs args)
        {
            var proxy = new WebProxy(_proxyUrl, true) { UseDefaultCredentials = false };
            return new HttpClientHandler { UseProxy = true,  Proxy = proxy};
        }    
        
    }

Please try this code, which I’d expect to work - basically you need your credential to know the client factory to use:

var scopes = new[]
{
    DirectoryService.Scope.AdminDirectoryDomainReadonly,
    DirectoryService.Scope.AdminDirectoryOrgunitReadonly,
    DirectoryService.Scope.AdminDirectoryUserReadonly,
    DirectoryService.Scope.AdminDirectoryDomainReadonly
};

var serviceCredentialFromFile = (ServiceAccountCredential) GoogleCredential.FromFile(sa_file).UnderlyingCredential;

// Specify the scopes, proxy and impersonation in the new initializer, all in one go, just for simplicity.
var initializer = new ServiceAccountCredential.Initializer(serviceCredentialFromFile.Id)
{
    ProjectId = serviceCredentialFromFile.ProjectId,
    Key = serviceCredentialFromFile.Key,
    User = user_email,
    HttpClientFactory = new ProxyHttpClientFactory(proxy),
    Scopes = scopes
};
var credential = GoogleCredential.FromServiceAccountCredential(new ServiceAccountCredential(initializer));

awesome, it works!!!

Okay, great. Will close this issue.
