[ERROR]  Encountered an exception while running action 'response_final_answer'.Bot will continue, but the actions events are lost. Please check the logs of your action server for more information.

The above exception was the direct cause of the following exception:

is it from my server or it is issue from my flow ? and what other types of error i may face ?

is there anyway i can handle this generic errors cause it stop the user from completing the flow, can i do something for the empty response ?

check this in your action file and it function.

As @nik202 stated it seems you have some broken code in the response_final_answer function call in your action server.
