IF you have connected the negative from the inverter to a chassis bolt rather than the negative battery post, none of the inverter current will pass through the sensor, so there will be no sensed current because the DC-DC converter in the car is doing all the work supplying your inverter.
Oh duh, yes of course. I'm definitely connecting the inverter '-' input to a chassis bolt; the folks at the thread I linked are most emphatic that you mustn't connect the inverter to the Leaf battery's negative terminal (because of that current sensor).

Thanks for the quick and helpful reply !

Well connecting the negative to chassis will not measure any current then because the battery is not providing the power, but the DC-DC is, and is not being measured.
I don't see why the big deal about running the current through the current sensor though. I imagine that any current passing through the hall effect current sensor would be compensated for by the convert's logic, so I don't see the point....but oh well.
