Rack::File is deprecated, please use Rack::Files instead - new Ruby on Rails project

When I create new Ruby on Rails (6.0.2.1) project with Hix on Rails Application Template, I get the following error:

Rack::File is deprecated, please use Rack::Files

What exactly causes it?

Solution

  • I resolved this issue by updating the gem rack:

    bundle update rack
