Im working with OAuth 0.3.6 and the linkedin gem for a Rails application and I have this issue where OAuth throws an error saying that OAuth::Problem (parameter_absent). The
I has similar problem and was wondering what is wrong. Finally got to know that I forgot to set the Environment variable on the production server that was serving the keys/secrets.
