We are in the process of enabling the NodeJS Auto-attach with UMA version 25.4.2.5.
We are observing behavior where the Auto-Attach is successful in approximately one in every 10 attempts.
Based on the logging, we believe that we have isolated what is causing the auto-attach to be unsuccessful.
Fixed with latest UMA image and in F158029 Nodejs auto-attach optimisation to support various command options during install.
