What Ruby, Rails and RSpec versions are you using?

Ruby version: ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin17]
Rails version: 6.0.0
RSpec version: 3.8

• rspec-core 3.8.2
• rspec-expectations 3.8.4
• rspec-mocks 3.8.1
• rspec-rails 3.8.2
• rspec-support 3.8.2

Observed behaviour

ActionView::Template::Error:
       wrong number of arguments (given 2, expected 1)
# ~/.rbenv/versions/2.5.1/lib/ruby/gems/2.5.0/gems/rspec-rails-3.8.2/lib/rspec/rails/view_rendering.rb:105:in `call'

Expected behaviour

The specs should all pass, (all pass with rails 5.2.3)

Investigation

It failed on this method EmptyTemplateHandler::call
https://github.com/rspec/rspec-rails/blob/master/lib/rspec/rails/view_rendering.rb#L105

class EmptyTemplateHandler
    def self.call(_template)
        ::Rails.logger.info("  Template rendering was prevented by rspec-rails. Use `render_views` to verify rendered view contents if necessary.")

        %("")
    end
end

There are arguments changes from rails
rails/rails@28f88e0#diff-562906215bf781788ec5aaf37e958cb8L307

-  code = @handler.call(LegacyTemplate.new(self, source)) 
+  code = @handler.call(self, source)
