I have running a daemon server to post the social network feeds on scheduled time.
Currently, I have issue while running daemon server which is written in node.js and express framework backed with mongodb.
Please see the following error which I got from heroku logs command.

As you can see that daemon server script run successfully but after that Heroku log showing me the boot timeout error.

fs.readdir('./Daemons/', function(err, files){

if(err){
cb(err)
} else {
if(stat.isFile()){
var daemon = require('./Daemons/' + file)(models)
agenda.define(daemon.name, daemon.options, daemon.job)
cb(null)
} else {
cb(err)
}
}
})
}, function(err){
if(err){
console.log("Error starting daemon server: ", err)
return
}
console.log("Starting daemon server")
agenda.start()
})
}
})
})
})
}
I have researched on web and found some solutions which suggest for this problem is to increase the web process time but did not find the place on Heroku where I can set this value.
