Environment Details
The following error is seen when running a workflow with macros, or an application.
Error: Join (1): Tool #79: XmlParse Error (2): the element Configuration is not properly closed.
Cause
The Action tool is configured to modify the Inner XML, and therefore the <Configuration> tag is not closed properly.
Resolution
Change the configuration of the Action tool to update the Outer XML.
This is necessary when you are including the <Configuration> tag in the value you are sending to the Action tool. Here is a visual guide to the difference between the OuterXML (in Green) and the Inner XML (in Purple) for the Configuration element you see selected above.
