Dashboard undefined safety status

I get a reply “UNDEFINED_SAFETY_MODE” from the dashboard command “safetystatus” on e-Series.
What is the possible robot state that can produce that undefined safety status? Should I treat it as a safety violation?

I could not find it in the dashboard manual. https://s3-eu-west-1.amazonaws.com/ur-support-site/42728/DashCommand.pdf
