Hi
I can't find a way to say it must find the batch on the first AE server? Can this be the issue?
=> correct.
You can not influence on which AE server is searched for the file, its depending on the WP it gets executed.
Solution attempts:
A) copy it from one AE Server to the other
B) use an UNC path where both Engines have access to.
Docu:
This script element always sends emails via the Automation Engine. Files that should be attached must be stored on the computer of the AutomationEngine or be accessible from there (UNC path).
