Python - GCP Cloud Function issue with getting yesterdays date

I have a requirement of getting yesterdays date in my GCP Cloud Function which is written Python 3.9

This is the snippet I am using

from datetime import datetime, timedelta
cur_dt = datetime.today()
str_dt = str((datetime.today() - timedelta(1)).strftime('%Y-%m-%d'))
print(cur_dt)
print(str_dt)

This is working fine in Jupyter notebook. But if I place this same code in my cloud function, it fails to compile.

This is the error message I am getting: - Function failed on loading user code. This is likely due to a bug in the user code.

Would be of great help if anyone can help me fixing this error. This is strange and I dont understand why CLoud function isnt accepting something that is working fine in Jupyter notebook

Many Thanks in Advance.

As mentioned you need to follow the Cloud Functions schema which requires an entrypoint function that takes in the request parameter. Here is a codelab that walks through setting up a Cloud Function.

Your code should be updated to the following:

# imports 
from datetime import datetime, timedelta

# entrypoint function with request param
def get_time(request):
  cur_dt = datetime.today()
  str_dt = str((datetime.today() - timedelta(1)).strftime('%Y-%m-%d'))
  # can still print here if you want
  return str_dt

If you are going through the UI make sure to update the entrypoint field to be get_time or whatever you name your entrypoint function.
