Question on how "relative_to" option works

[maxguuse]

So what I want to do is to get breadcrumbs to show relative path from what lsp considers root of project. What I do is:

local function get_relative_path()
	local workspace = vim.lsp.buf.list_workspace_folders()[1]
	local buffer_path = vim.fn.getcwd()

	if buffer_path:sub(1, #workspace) == workspace then
		return buffer_path:sub(#workspace + 2)
	else
		return buffer_path
	end
end

return {
		"Bekaboo/dropbar.nvim",
		lazy = true,
		event = {
			"LspAttach",
		},
		dependencies = {
			"nvim-telescope/telescope-fzf-native.nvim",
		},
		opts = {
			sources = {
				path = {
					relative_to = get_relative_path,
				},
			},
		},
	}

What I get instead of what I expect:

Whereas instead I expected to get rid of everything from /home to /nvim

What do I get wrong?

[maxguuse]

Well yes turns out my function is just wrong, refactored it like this:

local function get_relative_path()
	local workspace = vim.lsp.buf.list_workspace_folders()[1]
	if workspace and workspace ~= "" then
		return workspace
	end

	local buffer_path = vim.fn.getcwd()
	return buffer_path
end

Would happy to know if there's better way to do this though
