error when I quit help files

[Jaehaks]

Thank you for your efforts,

Whenever I quit opened help files, this mesage is invoked

It said that it needs to set filetype, but the help file is already set to 'help'
What I am missing?

this is my config

{
	-- rendering help using vimdoc treesitter
	"OXY2DEV/helpview.nvim",
	lazy = false, -- Recommended
	enabled = true,
	dependencies = {
		"nvim-treesitter/nvim-treesitter"
	}
}

That's strange. A help buffer shouldn't throw that error.

Did you do something like :e <some-file>(basically opening something on the buffer where the help file was being shown)?

I got what is the problem.
The error occurs whenever I close the help file with :bd. not :q
If I disable helpview.nvim, the :bd doesn't invoke error. so that is the reason why I think this way.
It is same situation when I quit the help file after opening a :e newfile .
