Stack level too deep after upgrading to 0.4.0

[juanpedrojose]

After upgrading to 0.4.0 here is what I get on almost each request.
Sometimes the page loads normally. Browser independent (thought It could be a chrome-extensions related issue but no), same exception stack using wget/curl.

SystemStackError - stack level too deep:

Created a kind of a mokey patch to fix that, some time ago, feel free to use it.

https://github.com/alekseyl/rails_panel

add this to a Gemfile:

gem 'meta_request', git: 'https://github.com/alekseyl/rails_panel.git', glob: '/meta_request/meta_request.gemspec'

and introduce proper initialiser file into intialisers filder, with content similar to:

MetaRequest::Event.configure { |config|
  config[:NOT_JSON_ENCODABLE] << ActiveRecord::ConnectionAdapters::PostgreSQLAdapter
}
