Hi,
I am using a commerce server orders adapter with BizTalk. It is running fine
however everyday I get an error from the Commerce server orders adapter and I
have to reset the host as this error fails BizTalk. The error I get is below;
The Messaging Engine received an error from transport adapter
"CommerceServerOrders" when notifying the adapter with the
BatchComplete event. Reason "Object reference not set to an instance of an
object.”
Then I get this error message that follows;
Failed submitting message to BizTalk. Message: . Stack trace: at Microsoft.CommerceServer.ServiceAgent.TryHandleWebMethodException(Exception ex, SoapHttpClientProtocol serviceProxy)
at Microsoft.CommerceServer.Internal.Orders.OrderServiceProxy.AuthorizedInvoke(String methodName, Object[] parameters)

at Microsoft.CommerceServer.Adapter.Orders.OrdersReceiveEndpoint.GetOrderGuids(Cookie commerceServerCookie, ArrayList& orderGroupIds)
at Microsoft.CommerceServer.Adapter.Orders.OrdersReceiveEndpoint.SubmitBatch().

Does anyone know what the cause of this message is

The receive endpoint will wake up periodically an issue a search to the web service for the set of objects that should be transferred to BizTalk. This stack trace indicates that this call is failing.
What do you mean when you say 'It is running fine...' Does the receive endpoint sometimes send orders but other times doesn't Are there corresponding errors on the CS machine
