Id Field Identified with an Asterisk in the Request Mapper of an Upsert Operation is Not Mandatory

If you configure the Salesforce Adapter as an invoke (target) connection in an integration and select Create, Update Or Delete Information on the Action page and the operation type as Upsert in the Adapter Endpoint Configuration Wizard, when you get to the request mapper, the Id field is marked with an asterisk (*) for the Upsert operation. This incorrectly implies that this field is mandatory. This field is not mandatory.
