Assume that you use Microsoft BizTalk Server 2010 or 2013. When you use a custom pipeline component to call Enterprise Service Bus (ESB) Transformation Service to transform messages in ESB Toolkit 2.1, the DocumentSpecName context property is set incorrectly on the output message, and you receive the following error message:
