How to do conversation with rasa bot using api

Hello, I have deployed the rasa x in AWS server following this tutorial. Now, I am trying to connect to the rasa x using the Chatbot Widget but, it’s throwing an error

. After surfing the web, I found this issue which was similar to mine. I tried it but, It’s also throwing the same error. It’s working fine Rasa Webchat UI. I don’t know where the error lies. Any help would be appreciated @JiteshGaikwad @Saul.

Thanks
