func ChmodRec(path string, di fs.DirEntry, err error) error {
if err != nil {
log.Fatal(err)
}
Your code does not check err argument in ChmodRec. This is an extract from official documentation:
WalkDir calls the function with a non-nil err argument in two cases.
First, if the initial fs.Stat on the root directory fails, WalkDir calls the function with path set to root, d set to nil, and err set to the error from fs.Stat.
Second, if a directory's ReadDir method fails, WalkDir calls the function with path set to the directory's path, d set to an fs.DirEntry describing the directory, and err set to the error from ReadDir. In this second case, the function is called twice with the path of the directory: the first call is before the directory read is attempted and has err set to nil, giving the function a chance to return SkipDir and avoid the ReadDir entirely. The second call is after a failed ReadDir and reports the error from ReadDir. (If ReadDir succeeds, there is no second call.)
Add this code to the beginning of the function. It can give you a hint:
func ChmodRec(path string, di fs.DirEntry, err error) error {
if err != nil {
log.Fatal(err)
}

您的代码在
chmodrec中不检查err参数。这是官方文档的摘录：将此代码添加到函数的开头。它可以给您一个提示：
