With JWT versions >=  1.0, JWT.decode is returning a token AND a header. Then, 
the call @token = JWT.decode(token, public_key, !!public_key) is no longer 
right.

There are 2 solutions, 

1) freezing gem dependencies to JWT ~> 0.1 
or 
2) update the call to 
@token, unnused = JWT.decode(token, public_key, !!public_key)

I am having the same problems that this user.

Thank you for elaboration.

I'll would prefer second solution since another gem in a project may rely on 
JWT versions >= 1.0...
