Environment variables not loaded anymore after upgrading to Rails 6.1.7.3

[pippokairos]

Description

We've been using the gem effectively up until Rails 6.1.7.2, but after upgrading Rails to version 6.1.7.3 and config to 4.1.0 the environment variables are not available anymore in the Settings.

Steps to reproduce

• Set the ENV usage to true and configure the other parameters

  Config.setup do |config|
  config.const_name = 'Settings'
  
  config.fail_on_missing = true
  
  config.use_env = true
  config.env_prefix = 'SETTINGS'
  config.env_separator = '__'
  config.env_converter = :downcase
  config.env_parse_values = false
  end

• Define an environment variable SETTINGS__TEST__VAR=1
• Run the Rails application on version 6.1.7.2 and config on version 2.2.3
  • Settings.test.var is defined
• Run the Rails application on version 6.1.7.3 and config on version 4.1.0
  • Settings.test.var is NOT defined

Is this issue still valid?
