Process is running from robot tray but while running through the trigger using unattended robot its getting failed

Process is running from robot tray but while running through the trigger using unattended robot its getting failed.

Its getting failed with some selectors issue, but after trying from Robot Tray its working perfectly on same VM.
Not sure what the issue.

Anyone have any idea?

Even I am facing similar kind of issue. Don’t know the exact reason. This maybe due to some environment settings of orchestrator as then environment in which robot is created is different from the environment in which your VM is kept open.
