Run tracker reset without display - dbus error

[Colin Law]

I am using tracker [1] and trying to run

tracker reset -f ~/

However, I am running it in a situation where there is no display
(from a node-red exec node). I get the error

Tracker-WARNING **: Failed to load SPARQL backend: Cannot autolaunch
D-Bus without X11 $DISPLAY

Is there some magic I can perform to allow this to work?
