Al validar los datos con Pydantic podemos asegurarnos de que tenemos, por ejemplo, exactamente una `list` de `str` con los scopes y un `str` con el `username`.

En lugar de, por ejemplo, un `dict`, o algo más, ya que podría romper la aplicación en algún punto posterior, haciéndolo un riesgo de seguridad.

También verificamos que tenemos un usuario con ese username, y si no, lanzamos esa misma excepción que creamos antes.

  The precise terms and conditions for copying, distribution and
modification follow.  Pay close attention to the difference between a
"work based on the library" and a "work that uses the library".  The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
