i am using raspberry pi 3 for vibration sensor with the following code:

#!/usr/bin/python
import RPi.GPIO as GPIO
import time

#GPIO SETUP
channel = 27
GPIO.setmode(GPIO.BCM)
GPIO.setup(channel, GPIO.IN)

def callback(channel):
        if GPIO.input(channel):
                print ("Movement Detected!")
        else:
                print ("Movement Detected!")

GPIO.add_event_detect(channel, GPIO.BOTH, bouncetime=300)  # let us know when the pin goes HIGH or LOW
GPIO.add_event_callback(channel, callback)  # assign function to GPIO PIN, Run function on change

# infinite loop
while True:
        time.sleep(1)

and produces an error like this:

Traceback (most recent call last):
File “/home/admin/project/project.py”, line 16, in
GPIO.add_event_detect(channel, GPIO.BOTH, bouncetime=300) # let us know when the pin goes HIGH or LOW
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
RuntimeError: Failed to add edge detection

how to fixed???

code will be running
