           var writestream = gfs.createWriteStream({ filename: filename, metadata:id });
             console.log(filepath);                                                       
             fs.createReadStream(filepath)
             .on('end', function() {

             })
            .on('error', function(err) {
             console.log("error encountered"+err);//ENOENT,open error  
             })
            .pipe(writestream);
            });

Why i am getting this error and how to resolve it?

ENOENT in this context means "No such file or directory." It means the filepath you are trying to read with createReadStream does not exist.
