Hard Reset corrupts git directory if failed when cloned using git cli

[rohitsakala]

Steps to Reproduce

• git clone --depth 1 https://git.rancher.io/charts --branch dev-v2.8 using Git CLI
• and then run the following Golang script

       openOptions := git.PlainOpenOptions{
		DetectDotGit: false,
	}

	// git clone --depth 1 https://git.rancher.io/charts --branch dev-v2.8
	repo, err := git.PlainOpenWithOptions("/Users/RSAKALA/temp/charts", &openOptions)
	if err != nil {
		fmt.Println(err)
		return
	}

	// Ensure

	// Hard Reset to commit
	resetOpts := git.ResetOptions{
		Mode: git.HardReset,
	}
	resetOpts.Commit = plumbing.NewHash("6a2b15c6f6487b4db16f10d8ec69bb8bf91dcabd")

	// Validate hashCommit and reset options
	err = resetOpts.Validate(repo)
	if err != nil {
		fmt.Println("hardReset validation failure: %w", err)
	}

	// Open new worktree
	wt, err := repo.Worktree()
	if err != nil {
		fmt.Println("hardReset failure on WorkTree: %w", err)
	}

	// Reset
	err = wt.Reset(&resetOpts)
	if err != nil {
		fmt.Println("hardReset failure: %w", err)
	} else {
		fmt.Println("Hard Reset Worked")
		return
	}

• Run git log

Output

fatal: bad object HEAD

@rohitsakala can you please share the error message you are getting? Please note that the code snippet above only gets the worktree and does not actually run the hard reset.
