Error in on_chain_start callback: 'name'

[stephenbpeters]

I'm running into an error.
Ubuntu 22.04, Python 3.10.6, langchain 0.0.198

In cell 8 of the notebook:

agent_executor.run("Describe the playlisttrack table")

Error in on_chain_start callback: 'name'

---------------------------------------------------------------------------
AuthenticationError                       Traceback (most recent call last)
Cell In[8], line 1
----> 1 agent_executor.run("Describe the playlisttrack table")

...and then many, many more lines in the error message. Anyone know what's going on here?
