What is the error (systemd doesn't run python script)?

Question

linux

In the /etc/systemd/systemfile vkbot.service, see below.

[Unit]
Description=VK_BOT
After=network.target

[Service]
Type=simple
ExecStart=/usr/local/bin/vkbot/bot.py
Restart=always

[Install]
WantedBy=multi-user.target

Then I enter the following commands into the console (PuTTy).
- systemctl daemon-reload
- systemctl enable vkbot.service
answer :

Created symlink /etc/systemd/system/multi-user.target.wants/vkbot.service → /etc/systemd/system/vkbot.service

- systemctl start vkbot
- systemctl status vkbot
answer :

/usr/local/bin/vkbot/bot.pyand ../usr/local/bin/vkbot/bot.pyare generally different paths. you should make sure that in your case they are identical (or not identical, and correct this matter).
what does the command ls -l /usr/local/bin/vkbot/typed in the terminal say?
