### originUser in configuration

The configuration doesn't allow for the field `originUser` as it has been moved to the new tracing functions.
For more information about tracing an origin user ID please see the section [Tracing of the services README file](../services/README.md#tracing)

### consumerSystemId -> originSystemId

```diff
	export class Configuration {
		membershipApi: null,
		offerDisplayNameOverrides: null,
		originSystemId: null,
-		originUser: null,
-		consumerSystemId: null,
+		originSystemId: null,
		paypalPaymentGateway: null,
		printFulfilmentApiKey: null,
		printInfoApiKey: null,
