Trouble with Step 11: Run The Notebook

[CynthiaJeaneKaye]

Hello, I hope someone can help me with this issue. Someone had this issue previously, but there was no follow-up on it. I entered my Websocket URL into the notebook, ran each cell in order from top to bottom, but I received this error:

DEBUG:websocket:----------------------- send: b'\x81\x97\xe7<4\xdd\x9c\x1eW\xb0\x83\x1e\x0e\xff\xa3ol\xfd\xafYU\xaf\x93~Q\xbc\x93\x1eI' DEBUG:websocket:send: b'\x81\x97\xe7<4\xdd\x9c\x1eW\xb0\x83\x1e\x0e\xff\xa3ol\xfd\xafYU\xaf\x93~Q\xbc\x93\x1eI' error from callback <function on_message at 0x7f4ac4764620>: 'botresponse' ERROR:websocket:error from callback <function on_message at 0x7f4ac4764620>: 'botresponse' File "/home/spark/shared/user-libs/python3.6/websocket/_app.py", line 346, in _callback callback(self, *args) File "", line 7, in on_message for item in msg["botresponse"]["messageout"]["context"]["entities_array"]: Unhandled exception in thread started by <function on_open..run at 0x7f4a941dbc80>

I suspect I will run into several more issues after this one is solved, so thank you in advance for the help!
