Scalar value for argument 'color' is not numeric

I got this with OpenCV 4.2.0 from cv2.rectangle, where start_point was a list, end_point was a tuple:

cv2.rectangle(rect_mask, start_point_2, end_point, 1, -1)

To fix:

cv2.rectangle(rect_mask, tuple(start_point_2), end_point, 1, -1)

Bottom line is that the OpenCV parses the args weirdly sometimes.
