has_key give an error if the value is set.

[neofloww]

if I have a value set for a
configatron.init do |init|
init.defaults.configure_from_hash (config: {file: './config.yml'})
end
configatron.init.defaults.config.file.has_key?(:exist)

When the value exists gives an error
block in initialize': undefined method has_key?' for "./config.yml":String (NoMethodError) from gems/ruby-2.3.1/gems/configatron-4.5.1/lib/configatron/store.rb:151:in do_lookup'
