not a directory

Error message

not a directory

What it means

ArchiveDir first os.Stat's the directory to archive; if the stat succeeds but the path is not a directory, it returns this sentinel error. It guards against archiving a regular file or symlink passed as the directory argument (a pre-existing os.Create(afname) would then clobber output).

Solutions

1. Verify the path with os.Stat and info.IsDir() before calling ArchiveDir.
2. If you meant to archive a single file, use ArchiveFiles/Archive instead of ArchiveDir.
3. Fix the path configuration to point to the actual artifact directory.

Example fix

// before
fsutil.ArchiveDir("/out/artifacts.tar", "/cfg/artifacts.yaml")
// after
if fi, err := os.Stat("/cfg/artifacts"); err == nil && fi.IsDir() {
    fsutil.ArchiveDir("/out/artifacts.tar", "/cfg/artifacts")
}

fi, err := os.Stat(dirPath)
if err != nil {
    return fmt.Errorf("cannot access %s: %w", dirPath, err)
}
if !fi.IsDir() {
    return fmt.Errorf("%s is not a directory", dirPath)
}

if err := fsutil.ArchiveDir(afname, dname); err != nil {
    if err.Error() == "not a directory" {
        return fmt.Errorf("configured artifact path %s is a file; fix config", dname)
    }
    return err
}

When it happens

Trigger: Calling fsutil.ArchiveDir (via archiveArtifacts) with a d2aname path that exists but is a regular file or symlink rather than a directory.

Common situations: Config pointing at an artifact file instead of the directory containing it, a directory replaced by a symlink after a deploy, or a path typo resolving to a file.
