Heroku environment variable not accessible, instead getting <%= ENV['MY_Setting'] %>

Have configuration in aws_setting.yml for different environments, as:

local: &local_settings
  enable_setting: true

heroku: &heroku_settings
  enable_setting: <%= ENV['MY_SETTING'] %>

test:
  <<: *local_settings

development:
  <<: *local_settings

staging:
  <<: *heroku_settings

In heroku added MY_SETTING kvp in staging's Config Vars

Loaded settings during initialization:

S3_SETTING = YAML.load_file("#{::Rails.root}/config/aws_setting.yml")[Rails.env]

Now after deployment to staging, instead of getting value for S3_Setting['enable_setting'] as true or false, receiving '<%= ENV['MY_SETTING'] %>' as text.

This is because you're just loading YAML. You also need to parse the content as ERB to get the value extrapolated.

YAML.load(ERB.new(File.read("#{::Rails.root}/config/aws_setting.yml")).result)[Rails.env]
