Hi Chip,
As an FYI we are posting a Hotfix update for RA 6.1 in the next few days and this will be 6.1.0.1051 which will include the following fix
Execute javascript action fails on RA agents’ version 6.1 that runs JRE8
This should address this issue.
We are also working on a new notification service which you will be able to subscribe to so you will get email notifications when patches and updates are posted, i will post more details on this soon.
Regards
Keith
