File not creating when using writeFile in nodejs

Question

Following is my code in update method for an event -

Event.findOneAndUpdate({_id: req.body._id}, updateData, function(err, event){
  if (err) {
    res.send({"message": "Something went wrong!", "err": err, "status_code": "500"});
  }
  else {
    console.log("----I AM IN ELSE STATEMENT----");
    // WRITE DATA TO LOG FILE 
    fs.writeFile("/logs/update-event.txt", event, function(err) {
      if(err) throw err;
        res.send({"message": "success", "data": event, "status_code": "200"});
    });
  }
});

And following is the error I am getting when updating -

/home/myproject/controllers/events.js:71
          if(err) throw err;
                        ^
Error: ENOENT, open '/logs/update-event.txt'

Though If am using the following code, it is creating File at the root of the folder-

fs.writeFile("update-event.txt", event, function(err) {

I tried by manually creating logs named folder but no luck.

Let me know what I am doing wrong here.

That obviously means, /logs/ directory is not existing: ENOENT = Error No Entry. — Axel Amthor

@AxelAmthor I tried by creating a logs directory but still the same error — Trialcoder

wrong path for the logs directory. /logs is located in the root of the filesystem, not your application. Otherwise use logs/update-event.txt w/o the leading / — Axel Amthor
