Custom alert action created via splunk add on builder is not working

[vijayameda5]

Hi Team,

i am trying to create a custom alert action using splunk add on builder.
this alert action will have 2 inputs for rest url and token. And also take payload from output of an alert.

Here is the code i am using.

but alert action is not working and no errors too in the code.

import os
# encoding = utf-8

def process_event(helper, *args, **kwargs):
"""
# IMPORTANT
# Do not remove the anchor macro:start and macro:end lines.
# These lines are used to generate sample code. If they are
# removed, the sample code will not be updated when configurations
# are updated.

[sample_code_macro:start]

# The following example gets the alert action parameters and prints them to the log
rest_url = helper.get_param("rest_url")
helper.log_info("rest_url={}".format(rest_url))

token = helper.get_param("token")
helper.log_info("token={}".format(token))

# The following example adds two sample events ("hello", "world")
# and writes them to Splunk
# NOTE: Call helper.writeevents() only once after all events
# have been added
helper.addevent("hello", sourcetype="sample_sourcetype")
helper.addevent("world", sourcetype="sample_sourcetype")
helper.writeevents(index="summary", host="localhost", source="localhost")

# The following example gets the events that trigger the alert
events = helper.get_events()
for event in events:
helper.log_info("event={}".format(event))

# helper.settings is a dict that includes environment configuration
# Example usage: helper.settings["server_uri"]
helper.log_info("server_uri={}".format(helper.settings["server_uri"]))
[sample_code_macro:end]
"""

helper.log_info("Alert action test started.")
helper.log_debug("debug message")
os.system("echo end of action")
