Hi i have this code that prompt the user for their location. I am using Botframework v4 and C#. I put the messenger quick reply in an attachment prompt.
if (response == "test location")
{
Activity reply = stepContext.Context.Activity.CreateReply();
reply.ChannelData = JObject.FromObject(
new
{
text = "loc",
quick_replies = new object[]
{
new
{
content_type = "location",
},
},
});
return await stepContext.PromptAsync(
ATTACHPROMPT,
new PromptOptions
{
Prompt = reply,
});
}
But after the user send its location. The bot crashes. How can i handle the return of the location so the bot won't crash? Here is the exeption
System.ArgumentNullException: Value cannot be null. Parameter name: utterance at Microsoft.Bot.Builder.AI.Luis.LuisRecognizer.d*23.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.Bot.Builder.AI.Luis.LuisRecognizer.d*10.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.BotBuilderSamples.BasicBot.d*24.MoveNext() in C:\Users\bguevarra\Desktop\finko\FinkoBot\Bots\BasicBot.cs:line 104 --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.Bot.Builder.MiddlewareSet.d*3.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.Bot.Builder.BotAdapter.d__13.MoveNext() == Oops Sorry, it looks like something went wrong.
