Can someone explain this error : Invalid custom record type key

Have you looked at the error XML?

I am using java to communicate with NetSuite.I get back a WriteResponse object after calling update, which has a reference to the status object which has three things code, message, type.The message is what I posted above

Without more context it's hard to tell. Seems like you have a controlling option for what record type to update not mapped at all or crossmapped

I get this issue when external ids are all wonky

@Brian Freytag I just found out that the internal id was wrong. It was because of some caching mechanism in our app. Thanks for your help
