An issue was found where a JOBP would result in an error due to variable type mismatch when executed via JSCH rather then executed manually.
In case of manual execution the Array defined in the PRPT resolves as expected.
When executed via JSCH, the PRPT apparently generates a string rather than an array.
Release : 12.3 and 21.0
The issue has been fixed with Automation Engine V21.0.6.
