busboy doesn't error when over limit?

I’ve got a busboy with options:

var busboyParser = busboy({
    limits: {
        fileSize: 1000000,       // 1 mb
        files: 2,
    }
});

My code is basically from the README:

    if (req.busboy) {
        req.busboy.on('file', function(fieldname, file, filename, encoding, mimetype) {
            var saveTo = path.join(os.tmpDir(), path.basename(fieldname));
            console.log("saved to " + saveTo);
            file.resume();
        });
        req.busboy.on('field', function(fieldname, val, fieldnameTruncated, valTruncated) {
            console.log('Field [' + fieldname + ']: value: ' + val);
        });
        req.busboy.on('finish', function() {
            console.log('Done parsing form!');
        });
        req.busboy.on('error', function() {
            console.log("ERROR");
        });
        req.pipe(req.busboy);
    }

But if I upload a file that’s over 1MB or upload more than 2 files, busboy won’t throw any errors. Instead busboy just proceeds to process the file(s):

Field [flowChunkNumber]: value: 3
Field [flowChunkSize]: value: 1048576
Field [flowCurrentChunkSize]: value: 1048576
Field [flowTotalSize]: value: 8210139
Field [flowIdentifier]: value: 8210139-guidepdf
Field [flowFilename]: value: guide.pdf
Field [flowRelativePath]: value: guide.pdf
Field [flowTotalChunks]: value: 7
saved to /tmp/file
Done parsing form!

How should I handle errors relating to the defined limits?

There is no event for fileSize limit?

@sam1111 You can simply unpipe busboy from the source stream if you want to halt parsing and possibly call busboy.removeListener('finish', myFinishListener).
