How can I filter different membership types from Join It to WooCommerce on a Starter Plan?

I created one in Python and mapped the fields but for some reason it isn’t running. Any ideas?

 

def generate_coupon_settings(input_data):

    # Check for necessary keys in input_data
    if not all(key in input_data for key in ['membershipName', 'email', 'expirationDate']):
        return {'error': 'Required keys missing in input data'}

    if input_data['membershipName'] == "GreenBuzz Friend (Zurich)":
        return {
            'couponName': input_data['email'],
            'couponAmount': '100%',
            'discountType': 'percent',
            'description': input_data['membershipName'],
            'dateExpires': input_data['expirationDate'],
            'usageLimit': 1,
            'emailRestrictions': [input_data['email']]
        }

    elif input_data['membershipName'] == "GreenBuzz Connect (Zurich)":
        return {
            'couponName': input_data['email'],
            'couponAmount': '100%',
            'discountType': 'percent',
            'description': input_data['membershipName'],
            'dateExpires': input_data['expirationDate'],
            'usageLimit': 2,
            'emailRestrictions': [input_data['email']]
        }

    elif input_data['membershipName'] == "GreenBuzz Green (Zurich)":
        return {
            'couponName': input_data['email'],
            'couponAmount': '100%',
            'discountType': 'percent',
            'description': input_data['membershipName'],
            'dateExpires': input_data['expirationDate'],
            'usageLimit': None,  # No limit
            'emailRestrictions': [input_data['email']]
        }

    return {
        'error': 'Unknown membership type or other unexpected issue'
    }

output = generate_coupon_settings(input_data)
