UiPath ReportSystemError Activity

My workplace recently migrated to Studio 2017.1.6435 and one of my modules written in 2016.1.6137 has an activity that reports as:


When I search for that activity in the activities panel, nothing is reported. I’m wondering if maybe this is an artifact of the upgrading process? The properties panel reports a DisplayName, TimeoutMs, AdditionalInformation, ErrorMessage and a Private checkbox, so something in the UiPath engine knows what it is and what it is supposed to do. It is also not listed in the activities guide.

Is there any available information on this activity?
