Trying to get stick V working

  • I am trying to get the Stick V working.
    I flashed it with the firmware 1.2 of target trace.
    I am using this code wit UIFlow Beta:
    from m5stack import *
    from m5ui import *
    from uiflow import *
    import unit


    rectangle0 = M5Rect(134, 104, 30, 30, 0xFFFFFF, 0xFFFFFF)
    Follow = M5Title(title="Title", x=3 , fgcolor=0xFFFFFF, bgcolor=0x0000FF)
    label0 = M5TextBox(5, 30, "Text", lcd.FONT_Default,0xFFFFFF, rotate=0)
    label1 = M5TextBox(70, 30, "Text", lcd.FONT_Default,0xFFFFFF, rotate=0)

    x = None
    y = None
    h = None
    w = None

    def buttonA_wasPressed():
    global x, y, h, w
    V0.setTrackAreaCoordinate(140, 100, 40, 40)

    Follow.setTitle('Follow the rabbit')
    V0 = unit.get(unit.TARGET_TRACE, unit.PORTB)
    while True:
    x = V0.getTrack_X()
    y = V0.getTrack_Y()
    h = V0.getTrack_Height()
    w = V0.getTrack_Width()
    rectangle0.setPosition(x, y)
    rectangle0.setSize(h, w)

    And getting the following error-Message:
    'module' object has no attribute 'TARGET_TRACE'
