@NeeluGeorge What is the reason for this? What is it solving? 'apply_conversation_reference' does this, except conditionally.

@tracyboehrer 'apply_conversation_reference' is using reference.activity_id
But TurnContext.get_conversation_reference(self.activity) called before this will map reference.activity_id with the original activity's id field.
Here we are passing self.activity in TurnContext.get_conversation_reference(self.activity) , not the activity we pass as argument

So our updated activity.id is left unused.This throws invalid ID error

@NeeluGeorge Thanks for that. I'll dig a little. I note that the Python get_conversation_reference is different from the DotNet and JS implementations.

@NeeluGeorge reference.activity_id should be TurnContext.activity.id. That happens in get_conversation_reference. But, Pythons get_conversation_reference is outdated, and that assignment should be conditional, which I will update. So doing this could potentially change that logic.

That doc states the Activity passed to update_activity should have its id set to the incoming activity.reply_to_id. Is there a value for that property?
