Debian Autorun service Systemd

Question

I'm writing a node.js App.

In this directory (/var/lib/cloud9/BBB_WebApp$) I have a package.json:

{
    "name": "MCP",
    "version": "0.0.0",
    "private": true,
    "scripts": {
        "start": "node ./bin/www",
        "build": "browserify ./app.js > ./public/bundle.js"
    },
    "dependencies": {
        "browserify": "^16.2.3",
        "cookie-parser": "~1.4.3",
        "debug": "~2.6.9",
        "express": "~4.16.0",
        "graceful-fs": "^4.2.4",
        "http-errors": "~1.6.2",
        "i2c-bus": "^4.0.9",
        "influx": "^5.4.0",
        "jquery": "^3.3.1",
        "morgan": "~1.9.0",
        "node-crc": "^1.2.2",
        "nodemailer": "^6.3.1",
        "pug": "2.0.0-beta11",
        "socket.io": "^2.1.1",
        "socketcan": "^2.5.0",
        "spi-device": "^2.0.9"
    }
}

The app works fine with

/var/lib/cloud9/BBB_WebApp$ npm run start 

or

/var/lib/cloud9/BBB_WebApp$ npm start

Now I want the app to start automatically after booting.
Therefore I use systemd.

$ sudo nano /lib/systemd/system/Start_MCP.service

.

[Unit]   
Description=Start MCP Service   
After=network.target   

[Service]   
User=debian   
ExecStart=/usr/bin/npm run start  
WorkingDirectory=/var/lib/cloud9/BBB_WebApp/  
#Restart=on-failure   
StandardOutput=syslog   
StandardError=syslog  
  
[Install]   
WantedBy=multi-user.target

.

$ systemctl daemon-reload  
$ systemctl enable Start_MCP.service  
$ systemctl start Start_MCP.service 

After a few seconds. The service stops.

$ systemctl status Start_MCP.service

The syslog shows the following lines:

What am I doing wrong ?
Why can I run the app with npm start normally but not with systemd service.
Why is bonescript not found.

Many thanks for your efforts.

The solution:
I can't explain why but reinstalling bonescript in the directory
...../BBB_WebApp$ npm install bonescript --save
has helped.
