JSONDecodeError when trying to call Orders().get_orders()

[Kwandransj]

The code is shown below, I'm new to using the sp-api. The end goal for this code is to get the Line items for the orders so we can run the customization information through another program. The credentials are in a local folder so that this can be transferred to the pc that will be running this script. It is currently on a testing machine.

import yaml
from yaml.loader import SafeLoader
from sp_api.api import Orders
from sp_api.util import load_all_pages, throttle_retry
from datetime import datetime, timedelta

with open('amazon_Credentials.yml', 'r') as f:
    credentials = yaml.load(f, Loader=SafeLoader)


@throttle_retry()
@load_all_pages()

def load_all_orders():
    orders = Orders(credentials=credentials).get_orders(CreatedAfter='2022-01-01')
    print(orders)
    return orders


for page in load_all_orders():
    for order in page.payload.get('Orders'):
        print(order)

This keeps giving me the error

JSONDecodeError
invalid control character at line 4 column 197 (char 218)

Any help on this problem would be greatly appreciated.

Thanks in advance
