Bug in Red Teaming LLM Applications Course

Hello guys, first of all thanks for the amazing Courses and platform. I have enjoyed it and learned a lot.

I have found a bug in the Red Teaming LLM applications course, in following link Red Teaming LLM Applications - DeepLearning.AI when running the llm_app.chat it triggers the following error:

`---------------------------------------------------------------------------
BadRequestError Traceback (most recent call last)
Cell In[9], line 1
----> 1 msg = llm_app.chat(“Hello!”)
2 print(msg)

File ~/work/L1/helpers/zb_app.py:135, in ZephyrApp.chat(self, message)
132 time.sleep(5)
133 return “API ERROR: Request Timeout”
→ 135 return self._chat_engine.chat(message).response`

Not sure if its just a temporary thing. Thanks for your support.
