Omniauth facebook - Auth info fields

Question

I am trying to setup omniauth for a website for login through facebook. The issue is facebook is not sending the 'info' field.

I have setup 2 facebook apps for different environment.

For one app the response has the fields

#<OmniAuth::AuthHash credentials=#<OmniAuth::AuthHash expires=true expires_at=14

In the development env I get the response

I wonder if it is a app level setting because the code is same for both. Only difference on the app side is one is API v2.3 and other is 2.4

Answer 1

There is difference when you use v2.3 and v2.4.

In your config/initializers/devise.rb file or wherever you have put your API key, you have to add info_fields, besides scope,

example

config.omniauth :facebook, APP["facebook_id"], APP["facebook_secret"],
    :scope => 'email,public_profile', info_fields: 'email,name'
