AttributeError: 'Sanic' object has no attribute 'is_running'

Can someone please help me? After I open rasa shell, I get the following problem: AttributeError: ‘Sanic’ object has no attribute ‘is_running’


Python == 3.8.12 rasa == 3.0.5 sanic == 21.9.2

Thank you

@gerrycheung type rasa --version while activating env ?

@gerrycheung could you tell me please what you have done to fix the issue? Thanks in advance
