What is the alternative for shell.raw_preview_action_cmd?

It seems in recent updates (actually have not updated nvim deps for months), the shell.raw_preview_action_cmd is gone, i have following snippet to show folder preview:

  opts.fzf_opts = {
    ["--preview-window"] = "nohidden,down,50%",
    ["--preview"] = fzflua.shell.raw_preview_action_cmd(function(items)
      if has_exa then
        return string.format(
          "cd %s ; eza --color=always --icons=always --group-directories-first -a %s",
          preview_cwd,
          items[1]
        )
      end
      return string.format("cd %s ; ls %s", preview_cwd, items[1])
    end),

Now it is not working because raw_preview_action_cmd is gone. is there an alternative method I can use?

Use shell.stringify_cmd.

Use shell.stringify_cmd.

Correct, but you can also set it to to { fn = func(…) end, type = cmd } and Fzf-lua will do that for you:
