I am trying to create a Customuser model and getting this error and i dont know where to add or change the related_name argument.

class CustomUser(AbstractUser):        
    age = models.PositiveIntegerField(null=True, blank=True)
    user_type = models.ForeignKey(
        UserType, verbose_name='User Type', on_delete=models.SET_NULL, null=True)
    level_master = models.ForeignKey(
        LevelMaster, on_delete=models.SET_NULL, null=True, blank=True)
    upload_image = models.ImageField(upload_to='media', null=True)
    
    
    # level_name = models.ManyToManyField(LevelMaster
    #     verbose_name="Level Name", max_length=150, unique=True, null=True, blank=True)
    l1=models.BigIntegerField(null=True,blank=True)
    l2 = models.BigIntegerField(null=True, blank=True)
    l3 = models.BigIntegerField(null=True, blank=True)


    created_at = models.DateTimeField(
        verbose_name='Created At', auto_now_add=True, null=True, blank=False)
    updated_at = models.DateTimeField(
        verbose_name='Updated At', auto_now=True, null=True, blank=False)
    

    class Meta:
        db_table = 'tbl_customeruser'
        managed = False
    
    def __str__(self) -> str:
        return self.username

In your settings.py file add

AUTH_USER_MODEL = 'YourAppName.YourModelClassName'
