如何使用 c# 在 microsoft botframework sdk V4 中获取异常的堆栈跟踪以及默认错误消息

Question

I have created a bot in microsoft botframework sdk v4 using c# and it is working well but when I got any error it simply showing "sorry, it looks like something went wrong". I want to get stack trace of the exception along with that default message. How can I get that.

thanks in advance,

I can't see why you want to show the whole stack trace as a response of your bot to a normal user, but in case this is for testing only you can simply modify the OnTurnError handler. This could usually be found in your Startup.cs class.

// Catches any errors that occur during a conversation turn and logs them.
options.OnTurnError = async (context, exception) =>
{
    logger.LogError($"Exception caught : {exception}");
    await context.SendActivityAsync("Sorry, it looks like something went wrong.");
};

From there you can use exception.StackTrace in your message.

If you are aiming to have this in production then don't do it . Instead go for a TelemetryClient like Application Insights and track exceptions there. This way you can post a nice and user friendly error message (if there is such) while still having some log information's in the backend to troubleshoot the issue.
