Causes an error when you reload! with rails 8.x context[:connection] ||= connection `<main>': undefined method `[]' for nil (NoMethodError)

Loading development environment (Rails 8.1.2)
3.3.6 :001 > Item.first;reload!
  Item Load (0.3ms)  SELECT `items`.* FROM `items` ORDER BY `items`.`id` ASC LIMIT 1 /*application='TestRails'*/
Reloading...
 => true
3.3.6 :002 > Item.first;reload!
(test-rails):2:in `<main>': undefined method `[]' for nil (NoMethodError)

          context[:connection] ||= connection
                 ^^^^^^^^^^^^^

Through trial & error I narrowed it down to this gem.

Through more I realized it's either of these default entries in the environments/development.rb file:

config.active_record.query_log_tags_enabled = true
config.active_record.verbose_query_logs = true

That causes it to cause this problem. Any suggestions welcome!

Hey!

Through trial & error I narrowed it down to this gem.

You mean that without anycable-rails everything works?

The only place we touch Active Record is here:

anycable-rails/lib/anycable/rails/railtie.rb

Line 134 in 393c68f

db_pool_size = ::ActiveRecord::Base.connection_pool.size

Though it should only run in the context of the AnyCable server, not Rails console. Still, disable this check via the disable_rpc_pool_size_warning configuration parameter worths a try.
