Auto shutdown of wave server and script via code

[n-srinidhi]

Hi!I have a wave app along with some engines running. I have an auto-shutdown function written to shutdown my python script at a given time.
It works on all my normal python scripts but in case of wave, the cmd window stays open with the following output on the console:

Exiting Script.
ERROR: The process with PID 18284 (child process of PID 22836) could not be terminated.
Reason: The process cannot terminate itself.
SUCCESS: The process with PID 22836 (child process of PID 9660) has been terminated.

The function i am using is as follows:

def seconds_until_given_time(time_string):
    # Get current time
    current_time = datetime.now()
    # Parse given time string into datetime object
    given_time = datetime.strptime(time_string, "%H:%M")

    #Adjust given time to be today if its earlier datetime
    given_time=given_time.replace(year=current_time.year,month=current_time.month,day=current_time.day)

    # Calculate time difference
    if given_time < current_time:
        # If given time is earlier than current time, add one day to given_time
        given_time += timedelta(days=1)

    time_difference = given_time - current_time
    # Calculate total seconds in the time difference
    total_seconds = time_difference.total_seconds()
    return total_seconds

def timed_shutdown():
    try:
        centra_log.info('Shutting down Wave Server Dashboard') 
        print("Exiting Script.")
        if os.name=='nt':
            #Find the PID of the current process
            current_pid=os.getpid()
            subprocess.run(['taskkill', '/F', '/T','/PID',str(current_pid)])
    except Exception as e:
        type_, value_, traceback_ = sys.exc_info()
        stack_trace = traceback.format_exception(type_, value_, traceback_)
        centra_error.error(stack_trace)
        sys.exit()

try:
    #Adding log for starting autoshutdown timer
    centra_log.info('Started auto shutdown timer')
    _AutoCloseTime = str(app_config=["AUTO-CLOSE-TIME"]).strip()
    waitSeconds=seconds_until_given_time(_AutoCloseTime)
    timer = threading.Timer(waitSeconds, timed_shutdown)  
    timer.daemon=True 
    timer.start()
except Exception as e:
    type_, value_, traceback_ = sys.exc_info()
    stack_trace = traceback.format_exception(type_, value_, traceback_)
    centra_error.error(stack_trace)

Is there a better way to shutdown all wave processes started with "wave run app.py" command?

Hi! I solved this!
I had to close the waved.exe as well as wave.exe running in my Task Manager via code, to resolve this.
