OAuth2::Error , Sign in issue with Oauth-facebook

Question

This is the error I am getting once I click on sign up and authorize the app with Facebook.

: {"error":{"message":"Error validating application. Invalid application     ID.","type":"OAuthException","code":101}}

I don't know how to fix this and where the error is coming from. Here is my omniauth.rb

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :developer unless Rails.env.production?
  provider :facebook, ['I_PUT_MY_API_ID_KEY'], ['I_PUT_MY_API_SECRET_KEY'],
  :scope => 'email, user_relationships, user_status,user_about_me publish_actions',    :display => 'popup'
end

Answer 1

mybe use
provider :facebook, ['I_PUT_MY_API_ID_KEY'], ['I_PUT_MY_API_SECRET_KEY'] to provider :facebook, "I_PUT_MY_API_ID_KEY", "I_PUT_MY_API_SECRET_KEY"

Answer 2

It worked without the brackets when I took off "[" and "]"
