undefined method `opts' for nil:NilClass

The following results in the error when making any request. Moving Roda.plugin :type_routing under App using plugin :type_routing does not cause an error.

require 'bundler/inline'

gemfile(true) do
  source 'https://rubygems.org'

  gem 'roda', '3.22.0'
end

require 'roda/session_middleware'

Roda.plugin :type_routing

class App < Roda
  # Replace `Roda.plugin :type_routing` with this
  # plugin :type_routing

  require 'securerandom'
  use RodaSessionMiddleware, secret: SecureRandom.alphanumeric(64)

  route do |r|
    r.root do
      r.get { '' }
    end
  end
end

run App.app

Looks like roda/session_middleware does not work if you load the type_routing plugin into Roda itself, because SessionMiddleware doesn't allocate a Roda scope (for performance reasons). This could definitely be fixed by allocating a Roda scope in roda/session_middleware, but I think I can figure out a way to avoid that.
