golang 递归函数？？？

leetcode 59.螺旋的方式生成一个n*n的matrix Example:

Input: 3 Output: [ [ 1, 2, 3 ], [ 8, 9, 4 ], [ 7, 6, 5 ] ]

func generateMatrix(n int) [][]int {
    matrix:=make([][]int,n)
    for i:=0;i<n;i++{
        matrix[i]=make([]int,n)
    }
    helper(matrix,n,1,0,n-1,0,n-1)
    return matrix
}

func helper(matrix [][]int,n,index,row0,row1,column0,column1 int){
    if index>n{
        return
    }

    //上边
    if row0 <= row1 && column0 <= column1{
        for i:=column0;i<=column1;i++{
            matrix[row0][i]=index
            index++
        }
    }

    //右边
    if column0 <= column1 && row0<row1{
        for i:=row0+1;i<=row1;i++{
            matrix[i][column1]=index
            index++
        }
    }
    //下边
    if row0 < row1 && column0 < column1{
        for i:=column1-1;i>=column0;i--{
            matrix[row1][i]=index
            index++
        }
    }
    //左边
    if row0<row1-1 && column0<column1{
        for i:=row1-1;i>row0;i--{
            matrix[i][column0]=index
            index++
        }
    }
    //递归内层
    helper(matrix,n,index,row0+1,row1-1,column0+1,column1-1)
}

我的运行结果是 [ [ 1, 2, 3 ], [ 8, 0, 4 ], [ 7, 6, 5 ] ]
debug过程中，发现在运行递归函数的时候报错，如下

报错：

大佬帮忙看看这是哪里错了？？？
