I set a python script as a "always on" task but it keeps running into the same exception. However, when I run the script as a "scheduled task" it works completely fine. Here is what the always on log shows...

Jul 11 03:44:38 newest_file = max(glob.iglob('*.csv'), key=os.path.getctime)

Jul 11 03:44:38 ValueError: max() arg is an empty sequence

Here is the code block this error relates to...

try:
        newest = max(glob.iglob('report*.csv'), key=os.path.getctime)
        dst = time.strftime("%H-%M %m-%d-%Y.csv")
        os.rename(newest, dst)
    except:
        print('Rename failed')
    else:
        print('Renamed')

I feel like this could be an issue with the time module or the working directory. Not really sure. Any thoughts on how I can get this error resolved?

Try using an absolute path when you define newest.
