TaskCanceledException: The request was canceled due to the configured HttpClient.Timeout of 100 seconds

[Sam7]

I often get this error. But other times it works without issues. Any ideas on how to change the timeout? Has anyone else had this issue?

System.Threading.Tasks.TaskCanceledException: The request was canceled due to the configured HttpClient.Timeout of 100 seconds elapsing.

I am also having this error sometimes

[Volumek]

could someone change it? if yes, please write in telegram, help @volume_k

We need to accept CancellationToken on async functions and pass it to the HTTP requests.

[memetic007]

a vote for making this user settable. I'm working with some big contexts in GPT-4 and they can take awhile. I have verified in OpenAI's Playground that in GPT-4 chat mode my prompts take well over 100 seconds to successfully complete.

I download the repository and made an ad-hoc fix, increasing the timeout to 1000 seconds. I rebuilt the nuget file and installed it locally. I tested it on my application and it works. At temporary fix to the problem. Much better would be a user parameter when creating a chat or other session.

in EndpointBase.cs:

protected HttpClient GetClient() { if (_Api.Auth?.ApiKey is null) { throw new AuthenticationException("You must provide API authentication. Please refer to https://github.com/OkGoDoIt/OpenAI-API-dotnet#authentication for details."); }

        HttpClient client;
        var clientFactory = _Api.HttpClientFactory;
        if (clientFactory != null)
        {
            client = clientFactory.CreateClient();
        }
        else
        {
            client = new HttpClient();
        }

        client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", _Api.Auth.ApiKey);
        // Further authentication-header used for Azure openAI service
        client.DefaultRequestHeaders.Add("api-key", _Api.Auth.ApiKey);
        client.DefaultRequestHeaders.Add("User-Agent", UserAgent);

        // Jim Rutt increased timeout to 1000

        client.Timeout = TimeSpan.FromSeconds(1000);

        if (!string.IsNullOrEmpty(_Api.Auth.OpenAIOrganization)) client.DefaultRequestHeaders.Add("OpenAI-Organization", _Api.Auth.OpenAIOrganization);

        return client;
    }

Why not instantiate your own HttpClient with whatever timeout settings you want, and pass that into the existing service constructors?

Do you have an example of this?

[winzig]

Of what? chatGPT can show you how to instantiate an HttpClient and set its timeout settings. Then you pass it into the constructor that accepts an HttpClient reference

[trippd6]

For people that are new to .NET like me, this is how I did it in C# (Warning, I have no idea what I'm doing and chatgpt did most of this work )

Add a reference to System.Net.Http to your project

Add the following lines in the right places in your project:

using System.Net.Http;

public class CustomHttpClientFactory : IHttpClientFactory
{
    public HttpClient CreateClient(string name)
    {
        return new HttpClient
        {
            Timeout = TimeSpan.FromSeconds(300)
        };
    }
}

OpenAIAPI api = new OpenAIAPI(myApiKey)
{
    HttpClientFactory = new CustomHttpClientFactory()
}

I have sort of the opposite issue. Some times the call hangs for 100 seconds and that's a long time if the answer is not coming. So I would need a timeout of maybe 10-15 seconds but only if it hasn't started answering yet. As soon as it is answering, then there should not be any timeout in my opinion.

Is there a way to understand that CreateChatCompletionAsync writing an answer or just stuck? If so maybe we can keep the time with Stopwatch and cancel the request manually.

[winzig]

Perhaps use StreamCompletionEnumerableAsync instead, so that you'd know if it was in the process of responding, versus just waiting for anything at all to come back?

[abhishek6616]

Do we have any fix for this?

[winzig]

I'm not sure this is a bug to be fixed. The SDK allows you to pass in your own HttpClient with your own preferences for timeouts, etc: https://github.com/OkGoDoIt/OpenAI-API-dotnet/issues/102#issuecomment-1563708070

The custom HTTP client is the "right" way to do this, but I should probably add a helper to make it easy to set a custom timeout and take care of this behind the scenes. The custom HTTP client is a bit clunky.
