RuntimeError: Conflicting edge detection already enabled for this GPIO channel #12

I try running the sample code and when I get to the line

keypad = factory.create_keypad(keypad=KEYPAD, row_pins=ROW_PINS, col_pins=COL_PINS)

I get the error

RuntimeError: Conflicting edge detection already enabled for this GPIO channel

Other than changing the row and column pins to match my actual wiring, the code is identical to the sample provided with the library. What am I missing here?

Cancel the above; I had assigned the same pin twice.
