Can't call two actions in on_project_selected

[alexhuot1]

Hi, Disclamer: I'm a total noob on vim/neovim/lua/etc!

I'm trying to setup telescope-project so that when a project is selected the folder is set as the CWD and find_files opens (default behavior):

local telescope = require('telescope')
local _actions = require("telescope._extensions.project.actions")

telescope.setup {
 ...
  extensions = {
    project = {
      hidden_files = true, -- default: false
      order_by = "asc",
      search_by = "title",
      on_project_selected = function(prompt_bufnr)
        _actions.find_project_files(prompt_bufnr, false)
        _actions.change_working_directory(prompt_bufnr, false)
      end
    },
    ...
  }
}

When I select a project I get this error:

E5108: Error executing lua ...-data/lazy/telescope.nvim/lua/telescope/actions/init.lua:343: attempt to index local 'picker' (a nil value)

Clearly, I'm doing something wrong, can someone help me out?

Thanks!
