I have a form which have a input type file with name "uploadfile". No error occurs while a file is selected and form is submitted. But having this error while I don't select a file and submit the form.

if(req.file('uploadfile')._files.length>0){
                var ques_file  = req.file('uploadfile');
                console.log('here');
                ques_file.upload({ 
                  saveAs: function(file, cb) {                       
                            cb(null, file.filename);
                          },
                  dirname: dirPath },function (err, files) {
                  if (err){                        
                    return res.serverError(err);
                  }else{                     
                    name =files[0].filename;
                    filename=name;                     
                    console.log("file : "+filename);

                  }
                });

` And in commad having this error

 events.js:72
        throw er; // Unhandled 'error' event
              ^

you should not use if statement for req.file(), you can check the length of array inside the function whenDone as in example below:

req.file('avatar').upload({
      saveAs: function(file, cb) {
        cb(null, file.filename);
      },
      dirname: uploadPath
    }, function whenDone(err, uploadedFiles) { //onUploadComplete
      if (uploadedFiles.length==0) {
        //if no file selected.
        sails.log.info('nothing selected');
        return res.view('showimage');
      }
      if (err){
        return res.serverError(err);
      } else{
        return res.view('showimage', {file:uploadedFiles});
      }
    });
