How to use node fluent-ffmpeg tp get video dimensions

I am using fluent-ffmpeg and i need to return width and height for the video

currently I am using on win the following code but with no result (data = undefined).

Any idea what am I doing wrong?

 ffmpeg('C:\Projects\test.mp4')
   .ffprobe(0, function(err, data) {
     console.log('file1 metadata:');
     console.dir(data);
     console.log(err);
   });
