attempt to concatenate local 'save_dir' (a nil value)

[Xifong]

When running :Telescope persisted
I get the following error:

Error executing Lua callback: ...al/share/nvim/lazy/persisted.nvim/lua/persisted/init.lua:210: attempt to concatenate local 'save_dir' (a nil value)

telescope checkhealth is fine:

telescope: require("telescope.health").check()

Checking for required plugins ~
- OK plenary installed.
- OK nvim-treesitter installed.

Checking external dependencies ~
- OK rg: found ripgrep 11.0.2

===== Installed extensions ===== ~

Telescope Extension: `fzf` ~
- OK lib working as expected

I'm using LazyVim so my config looks like:

return {
  {
    "nvim-telescope/telescope.nvim",
    dependencies = {
      {
        "nvim-telescope/telescope-fzf-native.nvim",
        build = "make",
        config = function()
          require("telescope").load_extension("fzf")
        end,
      },
      {
        "olimorris/persisted.nvim",
        config = function()
          require("telescope").load_extension("persisted")
        end,
      },
    },
  },
}

with a separate file lua/plugins/sessions.lua

return {
  {
    "olimorris/persisted.nvim",
    config = true,
  },

I get a similar error for :SessionDelete

E5108: Error executing lua ...al/share/nvim/lazy/persisted.nvim/lua/persisted/init.lua:66: attempt to concatenate field 'branch_separator' (a nil value)

	...al/share/nvim/lazy/persisted.nvim/lua/persisted/init.lua:168: in function 'delete'
	[string ":lua"]:1: in main chunk

Anyone got an idea what this is?
