log4js-node in nodejs not logging to file

Not a node expert, and this is the first time I'm using log4js-node.

I am trying to get my ERROR logs and any of my console logs to write to a log_file.log file with log4js on a nodejs server running Express. Here is my config file:`

{
  "replaceConsole": true,
  "appenders": [
  {
    "type": "file",
    "filename":"log_file.log",
    "maxLogSize":20480,
    "backups": 3,
    "category":"relative-logger"
  },
  {
  "type":"logLevelFilter",
  "level":"ERROR",
  "appender":{
    "type":"file",
    "filename":"log_file.log"
    }
  },
  {

    "appender": {
      "type": "smtp",
      "recipients": "[email protected]",
      "sender": "[email protected]",
      "sendInterval": 60,
      "transport": "SMTP",
      "SMTP": {
        "host": "localhost",
        "port": 25
      }
    }
  }]
}`

And here is how I'm requiring the application in my app.js file:

var log4js = require("log4js");
log4js.configure("log_config.json")
logger = log4js.getLogger();

I'm sending manual errors to log4js with this (I can get this to log to the console fine, just can't get the log_file written): 

logger.error('A mandrill error occurred: ' + e.name + ' - ' + e.message);

And I'm hoping jog4js catches the application's normal ERROR messages.

How do I get log4js to log to the log_file.log them send me an email of that log? I have installed nodemailer 0.7, fyi, to handle smtp.

Yes remove "category":"relative-logger" it somehow blocks the data transfer into your log file.. Or try something like this: 

// Setup Logging
log4js.configure({
    appenders: [
        { type: 'console' },
        { type: 'file', filename: '.\\logs\\PesaFastaArchiveData.log' }
    ]
});

The path is of-course the windows path.

maybe you could remove "category":"relative-logger" in your file appender.
