Trying to use the cyclic_checksum.py file in examples but getting error on Modifier callback

[Enginerd0]

Error:
Starting to send an auto-updating message every 100ms for 3 s
Traceback (most recent call last):
File "c:/Users/cyclic_checksum.py", line 63, in
cyclic_checksum_send(_bus)
File "c:/Users/cyclic_checksum.py", line 28, in cyclic_checksum_send
task = bus.send_periodic(msgs=message, period=0.1, modifier_callback=update_message)
TypeError: send_periodic() got an unexpected keyword argument 'modifier_callback'

Can anyone answer why I'm getting this error?
