Description
I'm following the start guide at: https://firebase.google.com/docs/functions/get-started?gen=2nd
At step 7, when testing the functions using the emulator, the addmessage function works fine, and triggers the makeuppercase function appropriately, but the makeuppercase call fails with an error related to event datetime:

FWIW, I was able to hack around it locally by modifying firestore_fn.py to use dateutil.parser instead and changing line 114:
import dateutil.parser as dateutil
Line 114:
event_time = dateutil.parse(event_attributes["time"])
Not sure if this would be the most appropriate fix for the repo, or if there's some other underlying root cause that should be addressed.
