Picroft gpio skill error?

I install this skill below

however installation unsuccessful due to error below
Any idea why?

File “/opt/mycroft/skills/picroft_example_skill_gpio/init.py”, line 56, in
import GPIO
File “/opt/mycroft/skills/picroft_example_skill_gpio/GPIO.py”, line 59, in
GPIO.add_event_detect(17,GPIO.BOTH,ButtonHandeler)
RuntimeError: Failed to add edge detection
2020-06-11 02:26:28.962 | ERROR | 24 | mycroft.skills.skill_loader:_communicate_load_status:286 | Skill picroft_example_skill_gpio failed to load

I google and find this
https://www.raspberrypi.org/forums/viewtopic.php?t=205327

But I’m running as root, and change gpio still issue
I found also need to add 99-com.rules but still issue

try to update the gpio user
if you are running picroft venv.
in the virtual environmnet sudo adduser mycroft gpio

sudo adduser mycroft gpio

After add this, I have different error now
