Hello All,

I have developed Rest API authentication using ueberauth , guardian and google auth provider.

Things are working as expected if I use the same route as specified in example.

  scope "/api/v0/auth/", ApiGateway do
    pipe_through :api

    get   "/:provider",           AuthController, :request

    get   "/:provider/callback",  AuthController, :callback
    post  "/:provider/callback",  AuthController, :callback

end

But If I modify the route to -

  scope "/api/v0/auth/", ApiGateway do
    pipe_through :api

    get   "/persons/oauth/:provider",   AuthController, :request

    get   "/:provider/callback",  AuthController, :callback
    post  "/:provider/callback",  AuthController, :callback

end

Then getting crash on console stating :
