Node.js csv-parse error mystery using Sails - node.js

Question

It processes most of the records from the .csv file. However, at the end I get this error with csv-parse node module and can't figure out why. It terminates my server so I need to resolve it. Please help

My Controller API
upload: function(req, res){
req.file('statData').upload(function(error, files){
var fs = require('fs');
var parse = require('csv-parse');
var csvData=[];
var lines = 0;
var filePath = sails.config.appPath + '/data/file.csv';
fs.createReadStream(filePath)
.pipe(parse({
columns: false,
delimiter: '\t',
skip_empty_lines: true,
relax: true
}))
.on('data', function(csvrow) {
csvData.push(csvrow);
})
.on('end',function() {
//do something wiht csvData
});
}
