Calling a protected NextJS API route from another Protected NextJS API route

I have a protected router , with withApiAuthRequired and I need to call it from an other api which also have withApiAuthRequired. but I get :

  error: 'not_authenticated',
  description: 'The user does not have an active session or is not authenticated'

Do I have to pass a token with the fetch request like this? headers: {Authorization: Bearer ${accessToken}}
this did not work btw.
