Peyton, it didn't work without the resistor and it did with it. Read that however you want.
It should have worked without the resistor, the sidecar has a pull-up resistor built in to it. I would double check all of your sensor connections as well as your digital sidecar connections, perhaps you don't have the power connections correct and your internal pull-up isn't receiving power. If you'd like to contact me directly I can try to direct you further.

Under normal circumstances, you can connect the dark output (DO) or light output (LO) of the light sensor directly to your input on the sidecar.
