Uncaught TypeError: Cannot read property 'substr' of null

I have a 139mb csv file I’d like to parse on the client

Papa.parse('../../data/OPD_140722_1.csv', {
    download: true,
    worker: true,
    step: function(row) {
        console.log("Row:", row.data);
    },
    complete: function() {
        console.log("All done!");
    }
});

Using this code I get the error: Uncaught TypeError: Cannot read property 'substr' of null from papaparse.js line 520, which is about the XHR header:

function getFileSize(xhr)
        {
            var contentRange = xhr.getResponseHeader("Content-Range");
            return parseInt(contentRange.substr(contentRange.lastIndexOf("/") + 1));
        }

So I guess the XHR doesn’t have a “Content-Range” header? The file is sitting on a server I fire up with python -m SimpleHTTPServer

Okay I’ll fire up a node.js server and get it to work
