Fault 2_2 Solution Code Error

Hello, new user here and I am going through the fault injection tutorials and have come to an error I am getting for the solution notebook for SOLN_Fault 2_2 - Voltage Glitching to Bypass Password. The error I am getting is in the 10th code block, which I will put below as well as the error output. Essentially it is an error with GlitchController, and I have not had any luck debugging.

gc.set_range("ext_offset", 0, 150)
if scope._is_husky:
    gc.set_range("width", 1900, 1901)
    gc.set_range("offset", 2000, 2500)
    gc.set_global_step([50])
    gc.set_step("ext_offset", 1)
else:
    if PLATFORM=="CWLITEXMEGA":
        gc.set_range("width", 43.5, 47.8)
        gc.set_range("offset", -48, -10)
        #gc.set_range("ext_offset", 7, 10)
        gc.set_range("ext_offset", 30, 45)
        scope.glitch.repeat = 11
    elif PLATFORM == "CWLITEARM":
        #should also work for the bootloader memory dump
        gc.set_range("width", 30.7, 36)
        gc.set_range("offset", -40, -35)
        scope.glitch.repeat = 7
    elif PLATFORM == "CW308_STM32F3":
        #these specific settings seem to work well for some reason
        #also works for the bootloader memory dump
        gc.set_range("ext_offset", 11, 31)
        gc.set_range("width", 47.6, 49.6)
        gc.set_range("offset", -19, -21.5)
        scope.glitch.repeat = 5
        
gc.set_step("ext_offset", 1)

Thanks!
