Persistent 500 Error calling Customer Billing Service with Python SDK for MS Advertising

Question

When I call the Customer Billing Service, with the code below:

billing_service = ServiceClient(  
    'CustomerBillingService',  
    authorization_data=authorization_data,  
    environment=ENVIRONMENT,  
    version=13,  
)  
  
predicates = {'Predicate': [{'Field': 'AccountId', 'Operator': 'Equals', 'Value': XXXXXXX}]}  
ordering = {'OrderBy': [{'Field': 'Id', 'Order': 'Ascending'}]}  
  
result = billing_service.SearchInsertionOrders(  
    Predicates=predicates,  
    PageInfo={'Index': 0, 'Size': 1000},  
    Ordering=ordering  
)  

I get an 500: Internal Server Error - my auth data is ok, as a call to the Customer Management Service is successful with the same data. Am I missing something?

Thanks in advance!

Trial and error has informed me that the PageInfo Size was set above the allowable limit (100). Sadly the basic error messaging that would feed this back is not in place. Oh well.
