ArgumentError: tried to create Proc object without a block - ruby-on-rails

Question

How can I resolve the following error:
$ rails db:migrate
Calling `DidYouMean::SPELL_CHECKERS.merge!(error_name => spell_checker)' has been deprecated. Please call `DidYouMean.correct_error(error_name,
spell_checker)' instead.
Calling `DidYouMean::SPELL_CHECKERS.merge!(error_name => spell_checker)' has been deprecated. Please call `DidYouMean.correct_error(error_name,

end
I am not understanding where is the error and how to fix it. There seems no error in my code. The logs with --trace are showing the error occured in lib/ruby/gems/3.1.0/gems/aws-sdk-core-2.9.24/lib/aws-sdk-core.rb:472:in `new' which callback = Proc.new .

You seem to be using an old version of Rails (5.1.7, EOL status) with a very new version of Ruby (3.1.2).
This error is probably a breaking change introduced in Ruby 3 that needs libraries to be adapted for it (see this case with Anycable here: https://github.com/anycable/anycable/issues/118)
As per this article : https://www.fastruby.io/blog/ruby/rails/versions/compatibility-table.html you cannot use a Ruby version higher than 2.6.0 with Rails 5.1.x
The solution would be to use Ruby 2.6.0 or to upgrade your Rails app to a newer version.
