Problem with autostarting EspruinoHub.service

Hello

I trying to get the EspruinoHub.service to autostart by following the instructions on the Github page. But when i run the command I get this:

pi@hassbian:~ $ sudo systemctl start EspruinoHub.service && sudo journalctl -f -u EspruinoHub

I can run the start.sh file normally by

./start.sh

and everyhting works as promised but I just can't get the systemdb to work.
Any ideas?

Edit: EspruinoHub is installed in /home/pi/EspruinoHub.
