uninitialized constant > ActionCable::Server::Configuration::ApplicationCable

Question

When I am running server its throwing error shown in logs below. I googled a lot but didn\'t get reason behind it. Somebody please put some light on it.

Gemfile

Answer 1

The error is related to not having the correct ActionCable files in your project. You need app/channels/application_cable/channel.rb that looks like this

module ApplicationCable
  class Channel < ActionCable::Channel::Base
  end
end

and app/channels/application_cable/connection.rb

module ApplicationCable
  class Connection < ActionCable::Connection::Base
  end
end
