`Definition` not shown up on the preview

[ghost]

Hello, with code like this, I didn't get the definition inside the preview part.

key_map.map({ "n", "i" }, "<leader>fr", function()
            require("telescope").extensions.repo.list({
                search_dirs = { "~/Projects" }
            })
        end, { silent = true, }, "Telescope", "list_repos", "[F]ind GitHub [R]epos")

The search_path has been set to ~/.config/nvim/lua, where my configs located in.
