MongoDB

Go

func Uploadfile(filename, filepath string) {
    data, err := ioutil.ReadFile(filename)
    if err != nil {
        log.Fatal(err)
        os.Exit(0)
    }
    bucket, err := gridfs.NewBucket(
        CNX.Database("VWS"),
    )
    if err != nil {
        log.Fatal(err)
        os.Exit(1)
    }
    uploadStream, err := bucket.OpenUploadStream(
        filepath,
    )
    if err != nil {
        log.Fatal(err)
        os.Exit(2)
    }
    defer uploadStream.Close()

    fileSize, err := uploadStream.Write(data)
    if err != nil {
        log.Fatal(err)
        os.Exit(3)
    }
    log.Printf("Data is transferred successfully. File size is %d M\n", fileSize)
}

func main() {
	file := "tony.mp4"
	filepath := "/home/bilal/Videos"
	UploadFile(file, filepath)
}

What I have tried:

I am trying to upload the data in mongodb. But it is giving me the error that no such file or directory. Although the path is correct.
