Getting error while creating/hitting admin endpoint

Using Django
1

I am trying be build an Token Authentication using DRF AuthToken. I want my own customisation for USER model, and this is how I have done. Now I want to login into Django Admin Panel, but when I hit that endpoint I get an error

django.db.utils.ProgrammingError: (1146, "Table 'roadmap.tutor_authuser' doesn't exist")

and when I am trying to createsuperuser its asks for my email and after entering that I am getting same error.

This is how my custom USER Model is,

class AuthUser(AbstractUser):
    ADMIN = 'A'
    STUDENT = 'S'
    TUTOR = 'T'
    ROLE_CHOICES = (
        (ADMIN, 'Superuser'),
        (STUDENT, 'Student'),
        (TUTOR, 'Tutor'),
    )
    username = None
    first_name = models.CharField(max_length=30, blank=True)
    last_name = models.CharField(max_length=30, blank=True)
    email = models.EmailField(max_length=254, unique=True)
    role = models.CharField(max_length=1, choices=ROLE_CHOICES, default=STUDENT)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = []

I also have done make migration and migrate successfully. And this is how my migration file looks like
