    There are some issues in that unit file:

    • The file contains two instances of Type=, one with simple and one with notify. It must contain only one such line and that must be of the proper type which in turn depends on how the executable /home/ubuntu/venv behaves. For daemons, often forking is used.
    • The filename given for StandardError should presumably be /home/ubuntu/logs/icengine/std_err.log and not /home/ubuntu/logs/icengine/std_err/log. Make sure the user ubuntu is able to write to that location and the directories exist. I reckon systemd won't create the path if it doesn't exist (although it'll create the file).
    • The syntax of StandardOutput= and StandardError= is wrong. According to the docs the sysntax is StandardOutput=file:/home/ubuntu/logs/icengine/std_out.log. Same for StandardError.
