Multiple authentication handler on 1 controller action not working properly

[fahmiardhianto]

The documentation stated that

If sign-in is successful, no other authentication method will be run, but if it doesn't (the authentication params were missing, or incorrect) then Devise takes control and tries to authenticate_user! with its own modules. That behaviour can however be modified for any controller through the fallback option (which defaults to fallback: :devise).

I created a controller that allow for Admin and user to update, following the doc to use fallback: :none

acts_as_token_authentication_handler_for Admin, fallback: :none, only: [:create, :update]
acts_as_token_authentication_handler_for User, fallback: :exception, only: [:update]

This works for the User, but when I try to send a request with valid Admin authentication, it always fails. Meaning that the authentication handler for User is still called.

Can someone give me a guide for this case?
