This is a “hot fix” to correct release 4.3.1
There was a file missing from last night’s release that broke the Script workflow. This file is added to 4.3.2 and the Script workflow has been retested.
If you can not get a Script workflow to work, or you can not use the “Test” button on the Script editor, then delete the workflow rule and recreate it (that will get you the updated workflow).
NOTICE: You may have to clear your browser cache for everything to work right in this or even the prior release.
