将字符串数组的单个元素初始化为Go lang中的另一个字符串变量

In this code, I read a text file for input (A1,B2) and Im using the split function to separate them at comma and store in strs, according to the function definition its returns a array in this case it is strs array, i want the first element in strs to be in currentSource and the second element to be in CurrentDest.I tried printing both the variables individually to check if its working,but the program exits after that and I get a error saying Panic: index out of range. Can anybody help me out..!!!

var currentSource string
var currentDest string

func main() {

    file, err := os.Open("chessin.txt")
    if err != nil {
        fmt.Println(err)
    }
    defer file.Close()
    scanner := bufio.NewScanner(file)
    for scanner.Scan() {
        strs := strings.Split(scanner.Text(), ",")

        currentSource = strs[0]
        currentDest = strs[1]
}

    This works

    var currentSource string
    var currentDest string
    
    func main() {
    
        file := "A1,B2
    "
        scanner := bufio.NewScanner(strings.NewReader(file))
        for scanner.Scan() {
            strs := strings.Split(scanner.Text(), ",")
    
            currentSource = strs[0]
            currentDest = strs[1]
    
            fmt.Println(strs)
        }
    
    
    }
    

    Are you sure your file (chessin.txt) it is ok?
