when i try to print the row, it returns nil. pl see below. it means
that this tool could not parse the data.

The "nil" returned is the return value of your puts() call, shown by
IRb.

The issue is that you are using FasterCSV.new(). It's intended for
when you want to pass in your own IO-like object. You are passing in
the path of a file to open though, so you want FasterCSV.open().
