Error: { "detail": "Authentication credentials were not provided." }

Hello community enter image description here I have a problem:

When i want to get into information in postman, This sends me the next error: "detail": "Authentication credentials were not provided."

Attach: The code in Django

1. Settings.py in (A) that shows the REST_FRAMEWORK REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': (

   'authentication.customJWTAuthentication.CustomJWTAuthentication', ), 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.IsAuthenticated', ), }

2. Views.py in (B1 and B2) that indicates the code POST

   from django.shortcuts import get_object_or_404 from rest_framework.response import Response from rest_framework.decorators import api_view, permission_classes from rest_framework import status from roles.models import Role from roles.serializers import RoleSerializer from users.models import User, UserHasRoles from users.serializers import UserSerializer import bcrypt from rest_framework_simplejwt.tokens import RefreshToken from rest_framework.permissions import AllowAny from django.conf import settings`

   Create your views here.

   GET -> OBTENER

   POST -> CREAR

   PUT -> ACTUALIZAR

   DELETE -> BORRAR
