Cron job return null

[Bold-maverick]

newbie here 👋
I'm trying to deploy my first micro using Deta, however, I'm not sure how to correctly set up the cron job. (this is my first cloud deployment ☺️)
basically, my script is to send an API call and then add the data to a spreadsheet:

def add_to_airtable(title=None, author='', url=''): if title is None:

So this is the only function I have in my code, with the get request outside of this function, and I have no idea how to integrate everything into the cron code

If I try the code below nothing happens:
@app.lib.cron() def cron_job(event): add_to_airtable()
