Anyone delt with a 08 Error on the Revv1?

Greetings, my bike just died all of a sudden and the display is indicating a 08 error, which is either cable issue of hall sensor on motor. Wondering if it is worth trying to fix the sensor or is it time to buy a new motor? There is a slight nick of cable behind the disk brake explosing a green wire, it doesnt look like the wire is cut, could that be the issue? thx
