It doesn't open file if I run my script from systemctl

[vsile]

I use next service file;

[Unit]
Description=Goserver

[Service]
Type=simple
Restart=always
RestartSec=3

Environment=GOPATH=/home/user/goserver/
Environment=BROWSER=gvfs-open
WorkingDirectory=/home/user
ExecStart=/usr/bin/go run /home/user/goserver/totalmanager.go

[Install]
WantedBy=multi-user.target

The script with open-golang is inside totalmanager.go

If I run my script "go run goserver/totalmanager.go" it works!

But if I use "sudo systemctl start totalmanager.service" it doesn't work!
May be something wrong with Environment?

I have not tried this myself, but try:

[Service]
User=user

to start the service as your user, so it knows who to open the link for.
