ObjectIsReadOnly on checkout

Question

I have a program that checks out images and checks in images. It failed today with an exception: CheckOut Exception [-102009] Unable to complete your request, you are not allowed to alter object "GUID-"... 
 A few minutes later, the same user doesn't experience this error. 
 Do you know what the error means? It's not one of the already checked out errors.

Hi Kendall, 
 The error comes from the business logic - so WCF-SOAP, ASMX-SOAP or WebClient-REST will all give the same answer. 
 The generic error is: ObjectIsReadOnly -102009 Unable to complete your request, you are not allowed to alter {object} ";{objectname}";. {reason} [c:{cardid} ce:{cardelement} ct:{cardtype}] 
 The error message is reused across object types (cardtype) to indicate that you do not have enough privileges at that moment in time. So all parameters matter to make a distinction. Typically it is about missing/mismatch on USERGROUP (so your user profile versus the object you are accessing). 
 Best wishes, Dave
