dry-view: ArgumentError: wrong number of arguments (given 3, expected 1..2)

Describe the bug

When I try to load the following code:

require "dry/view"

class ArticleView < Dry::View
  config.paths = [File.join(__dir__, "templates")]
  config.layout = "application"
  config.template = "articles/show"

  attr_reader :article_repo

  def initialize(article_repo:)
    @article_repo = article_repo
  end

  expose :article do |slug:|
    article_repo.by_slug(slug)
  end
end

I receive the following error:

ArgumentError: wrong number of arguments (given 3, expected 1..2)
