Scalable minds Chatroom for Rasa Core v0.11


I have been using scalable minds’ webchat component for Rasa ( and have updated my version of rasa_core to 0.11.1. I was wondering if anyone knows what changes need to be made to the chatroom code in rasa_utils in order for this component to work with this version of Rasa core? I have been trying to make some changes to, to make it similar to the new, but I am still getting an error. Thanks in advance for any help.

At the moment, when trying to run, I get the following error:
