Promo requires concealer

[FeiyouG]

Prerequisites

• I am using either 0.7 stable with the 0.0.12 tag or the latest compiled Neovim version
• I am using the latest version of the plugin

Neovim Version

0.8.2

Neorg setup

return {
	"nvim-neorg/neorg",
	dependencies = { { "nvim-lua/plenary.nvim" } },
	run = ":Neorg sync-parsers", -- This is the important bit!
	config = function()
		require("neorg").setup({
			load = {
				["core.defaults"] = {},
			},
		})
	end,
}

Actual behavior

When indent a list with >>, the following error is thrown:

Error executing Lua callback: ...youguo/.local/share/nvim/lazy/neorg/lua/neorg/events.lua:136: attempt to index local 'event' (a nil value)
stack traceback:

and the following warning is shown:

.../.local/share/nvim/lazy/neorg/lua/neorg/events.lua:105
Unable to create event of type core.norg.concealer.events.update_region . Returning nil...

Expected behavior

I expect>> to increase the indentation level for the current object correctly.

Steps to reproduce

1. Reuqire only core.default modules
2. Indent an object with >>

Potentially conflicting plugins

As I look through the implementation of core.promo, I found it actually requires core.norg.concealer to broadcast the event.
I might be wrong as I am very new to neorg (I literally started using it this morning).

Other information

No response

Help

Yes, but I don't know how to start. I would need guidance (check question below)

Implementation help

I think the best solution is to check whether the concealer module is loaded before creating and broadcasting a core.norg.concealer.events.update_region event with promo, but I am not 100% this is the preferred approach.

You're right, it shouldn't be like this :)

It should be fixed in the latest commit! If it still fails then feel free to reopen
