I found the following change fixes the errors.

Thank you for the insightful report. I appreciate the detailed information, which has helped me understand the main problem.

In Ruby 2.7, some API tests fail due to changes in how Module#include and Module#prepend work from Ruby 3.0 onwards. In Ruby 2.7, the order in which modules are included affects whether include/prepend functions properly in certain cases. This issue is related to https://bugs.ruby-lang.org/issues/9573 .

Since trunk revision r22488, ActionView::Rendering has been prepended with an anonymous module in config/initializers/10-patches.rb. However, ActionView::Rendering is already included in ActionController::Base. Thus, in Ruby 2.7, prepending ActionView::Rendering at the beginning with this anonymous module seems to be ineffective, and the API tests fail to produce the expected context-type.

Implementing the following changes will allow the API tests to pass in Ruby 2.7.

diff --git a/config/initializers/10-patches.rb b/config/initializers/10-patches.rb
index adac86583..7694fb60d 100644

     def rendered_format
       if lookup_context.formats.first == :api
         return request.format

I hope this proves helpful.
