Standard Support for Mule 4.1 ended on November 2, 2020, and this version of Mule reached its End of Life on November 2, 2022, when Extended Support ended. Deployments of new applications to CloudHub that use this version of Mule are no longer allowed. Only in-place updates to applications are permitted. MuleSoft recommends that you upgrade to the latest version of Mule 4 that is in Standard Support so that your applications run with the latest fixes and security enhancements. |
Through the graphical UI of the Transform component you can do the tasks below. Each task will produce the DataWeave source code that describes the action.

Select the corresponding input element.
A trash can icon

Set a Fixed Value or Function
-
Double click on a field (that doesn’t have any children) in the output tree. This adds a function icon
