/Users/thanos/.gem/ruby/3.2.1/bundler/gems/sneakers-803d60deb729/lib/sneakers/tasks.rb:13:in `block (2 levels) in <main>'A possible explanation
As per Rails Guides zeitwerk is the only autoloader mode and the config.autoloader = method is deprecated. Although they don't state anything about whether the reader is still available, it seems it is not.
A possible solution
Maybe instead of using Rails.application.config.autoloader, we could use the following check as described in rails guides.
Rails.autoloaders.zeitwerk_enabled?
Or maybe use a different check based on rails version? I don't know what could more future proof.
@thanosbellos if Rails Guides recommend using a predicate, then we should do that. Please submit a PR?
Closed by #474.
@michaelklishin thanks for your quick response. Have a nice day!
