AttributeError: module 'httpx' has no attribute 'AsyncClient'

While i am running the action server, it displays AttributeError: module ‘httpx’ has no attribute ‘AsyncClient’ . please help me out i am trying to solve this from a week.

Looking at their current documentation it looks like there should be an AsyncClient… Have you tried updating? It could have been added recently?

It displays this type of message, if rasa train may works then rasa actions displays this error, else vice-versa.
