I am running a bot bot with Bot Framework technology in c #, sometimes it generates an exception of typo System.Exception that has the following message: invalid need: expected Call, have Poll
According to the Stack Trace, the error is generated in the following method:
private async Task ShowRequiredDestinationTripAsync(IDialogContext context)
{
if (this.tripModelDialog.DestinationTrip == null)
{
await context.PostAsync($"Hacia donde te diriges?(solo escribe el nombre de la ciudad de destino, ej. Villao)");
context.Wait(this.ValidationDestinationTrip); //aquí es el error
}
else
{
await ShowRequiredDateTripAsync(context);
}
}
When testing in the development environment, this does not happen; and in the productive environment happens on some occasions
