NoMethodError: undefined method `[]' for nil:NilClass since Ruby 3.3.0dev #1856
Description
Recently, one of Rails CI testing Active Job integration tests with resque has been failing. https://buildkite.com/rails/rails/builds/93710#01863c1c-deb5-4ec2-9169-636a5ffbcbbc/1359-1416
Based on the git bisect or Ruby repository, this behavior change has been introduced via ruby/ruby@194520f
So far I am not sure how to address it from Ruby side or resque side though, I'm opening an issue here.
Steps to reproduce
Install `ruby 3.3.0dev` includes https://github.com/ruby/ruby/commit/194520f80e1cdb71faa055d731450855a1ddb8d1
git clone https://github.com/resque/resque.git
cd resque
bundle install
bundle exec rake test
Expected behavior
All of tests should pass.
Actual behavior
283 runs, 490 assertions, 8 failures, 80 errors, 0 skips
These failures and errors are triggered since ruby/ruby@194520f
$ bundle exec rake test
