Using nodejs app as Windows Service causes EPERM-4048 ERROR - node.js

Question

I'm using "node-windows" for creating service that will run my app.js server
on windows.
This is the code that makes the service (using node-windows module)-
var Service = require('node-windows').Service;
// Create a new service object
var svc = new Service({
name:'Demo Landing Page',
description: 'The nodejs.org example web server.',
script: 'app.js'
});
// Listen for the "install" event, which indicates the
// process is available as a service.
svc.on('install',function(){
svc.start();
});
svc.install();
All works fine with the script but this line for reading directory content-
fs.readdir([PATH], function(err, builds)
This is the error that I get -
{Error: EPERM: operation not permitted, scandir [PATH]
errno: -4048,
code: 'EPERM',
syscall: 'scandir',
path: 'app.js' }
But If I run not as a service - just as-
node app.js
all works fine, permissions are fine.
What can I do in order to fix this?
Or maybe there is another option for running nodejs on windows server?
Thanks!

Answer 1

Right click on service
open its properties
check what account its using under logOn
Either try this in service above code
svc.logOnAs.domain = 'mydomain.local';
svc.logOnAs.account = 'username';
svc.logOnAs.password = 'password';
or you can directly add credentials and restart the service
