Generated jwt token is not validated in API (djangorestframework-simplejwt)

Hello,

I am using the django-saml2-auth with JWT to integrating to django-restframework. In my project I am using too djangorestframework-simplejwt. However, the jwt token generated after saml authentication in Azure AD is not validated in my API.

When I try to access some endpoint of my API:

{
  "status": "error",
  "code": 401,
  "data": null,
  "message": "Given token not valid for any token type"
}

Some points of my settings:

SIMPLE_JWT = {
    "ACCESS_TOKEN_LIFETIME": timedelta(days=1),
    "REFRESH_TOKEN_LIFETIME": timedelta(days=2),
    'AUTH_HEADER_TYPES': ('Token',),
    'UPDATE_LAST_LOGIN': True,
    "TOKEN_OBTAIN_SERIALIZER": "myapi.token.serializer.CustomTokenObtainPairSerializer",
    "ALGORITHM": "HS256",
}

SAML2_AUTH = {
    'METADATA_LOCAL_FILE_PATH': '/app/static/PSAT-Core-Saml2.xml',

    'KEY_FILE': '/app/static/chave_privada.key',
    'CERT_FILE': '/app/static/certificado.crt',

    'DEBUG': True,
    'DEFAULT_NEXT_URL': '/api',

    'CREATE_USER': 'TRUE',
    'NEW_USER_PROFILE': {
        'USER_GROUPS': [],
        'ACTIVE_STATUS': True,
        'STAFF_STATUS': False,
        'SUPERUSER_STATUS': False,
    },
    'ATTRIBUTES_MAP': {
        'email': 'name',
        'username': 'name',
        'first_name': 'givenname',
        'last_name': 'surname',
    },

    'ASSERTION_URL': 'http://localhost:8000', # Custom URL to validate incoming SAML requests against
    'ENTITY_ID': 'http://localhost:8000/saml2_auth/acs/', # Populates the Issuer element in authn request
    'NAME_ID_FORMAT': 'urn:oasis:names:tc:SAML:2.0:nameid-format:persistent', # Sets the Format property of authn NameIDPolicy element
    'USE_JWT': True,
    'JWT_ALGORITHM': 'HS256',  # JWT algorithm to sign the message with
    'JWT_SECRET': 'your.jwt.secret',  # JWT secret to sign the message with
    'FRONTEND_URL': 'http://localhost:3000/login',
    'WANT_ASSERTIONS_SIGNED': True,
    'AUTHN_REQUESTS_SIGNED': True,
    'WANT_RESPONSE_SIGNED': True,
    'TOKEN_REQUIRED': False
}

I'm glad for any help.
