Creating a feedback form tutorial issue

What I’m trying to do:
I’m currently doing the feedback form tutorial and I keep getting the following error as soon as I create the server module

Code for the server module:

@anvil.server.callable
def add_feedback(name, email, feedback):
  app_tables.feedback.add_row(
    name=name, 
    email=email, 
    feedback=feedback, 
    created=datetime.now()
  )
  

Have found the issue, need to upgrade or get a license to run the server module. Otherwise it breaks!
What’s the point in having a tutorial if you need to upgrade to run even the most basic things?

You should be able to run that tutorial on the free version. There’s nothing there that uses paid features.

Unless you tried to change the Python version being used in the server from the basic version that free accounts support?
