Lesson 1: Multi-Agent Conversation and Stand-up Comedy getting 2 errors I cannot find a fix to correct them

I am running this code locally and I am getting errors

reply = agent.generate_reply(
messages=[{“content”: “Tell me a joke.”, “role”: “user”}]
)
print(reply)

Getting two error when I run the above code

Sometimes I get this one
Cell In[17], line 2
messages=[{“content”: “Tell me a joke.”, “role”: “user”}]
^
SyntaxError: invalid syntax. Perhaps you forgot a comma?

Sometimes I get this error message
IndexError: list index out of range

Does anyone know how to fix these issues

NOTE: I had no problems with the 1st 2 code blocks when I ran them

Thank you
