Service keeps returning false

When I call my service, even though I have made the response true in the callback function, it returns as false!

Here’s my code:

import rospy
from services_quiz.srv import BB8CustomServiceMessage, BB8CustomServiceMessageResponse
from geometry_msgs.msg import Twist

def my_callback(request):
response = BB8CustomServiceMessageResponse()
response.success = True
return response

rospy.init_node(‘service_server’)
my_service = rospy.Service(’/move_bb8_in_square_custom’, BB8CustomServiceMessage , my_callback) # create the Service called my_service with the defined callback

my_pub = rospy.Publisher(’/cmd_vel’, Twist, queue_size=1)
move = Twist()
rate = rospy.Rate(1)
rospy.spin() # maintain the service open.

The response in the terminal is:

success: false

The BB8CustomServiceMessage.srv file is:

float64 side
int32 repetitions

bool success

Thankyou in advance for your help!!

I also tried editing the callback function:

#! /usr/bin/env python

import rospy
from services_quiz.srv import BB8CustomServiceMessage, BB8CustomServiceMessageResponse
from geometry_msgs.msg import Twist

def my_callback(request):
print(“hello”)
return

rospy.init_node(‘service_server’)
my_service = rospy.Service(’/move_bb8_in_square_custom’, BB8CustomServiceMessage , my_callback)
rospy.spin()

and am still getting a similar response, although it is now returning True
