basically its throwing

I read this alsoSO-related question I don't get it exactly as conveyed there.

Please clarify, what am I missing ...

You need to add the UserManager to the User mode:
class User(AbstractUser):
# …
objects = CustomUserManager()
Without specifying the manager, it will fallback to the UserManager [Django-doc], not the CustomUserManager.

Is it because of improper jwt token configuration or user model?

Have you tried retrieving your User model with get_user_model?
from django.contrib.auth import get_user_model
User = get_user_model()

Django Integrity Error- Unique Constraint Failed

Trying to create a simple launch page for my website to collect email addresses. When the user goes to submit, it is providing the following error (traceback below)--Unique Constraint Failed---accounts.user.username. I figured maybe this has to do with the email address entered overlapping with username, but as you can see in my accounts model--the username is created from the email. (Note the entire User and User Profile models are not being utilized throughout my site yet, but just preparing for future usage). Any help is appreciated. Thanks

Your User model has a username field which requires unique=True which is the cause of your problem. Now you might be having a user having a username field as '' which is default. Since you already have one user with this username you can't have another user with this field. You should check that user already exists in the db or not also you have to enter some username with a user don't use default with unique=True its a really bad design and always fails.

since you are using username = email.split('#')[0] to get the username for the user. It is possible that two different email would give you same value for the username. For example example#abc.com and example#def.com. What you need to do is figure out some other algorithm to set the username or a good idea can be to user the email as username.

In your Accounts app model try this user.save(using=self._db) , this might help you

Issue with createsuperuser when implementing custom user model

I am trying to implement my own custom user model in Django 1.6 but I am getting this error.
Traceback (most recent call last):

return user
It seems like this would be fairly straight forward but I can't seem to figure out why I am getting this error in the first place because I do have email specified in my create_superuser function. I have looked through several tutorials online and can't see how this is implemented differently. Can someone explain what I am doing wrong?

Looking at the code for the management commands, it only prompts for fields in the user model's REQUIRED_FIELDS attribute (as well as username). That attribute contains email by default in AbstractBaseUser, but if you have overridden it - or not inherited from that model in the first place (which you should be doing) - then email will not be prompted, and not passed to the create_superuser method.

class User(AbstractBaseUser, PermissionsMixin):
username = models.CharField('username', max_length=150, unique=True)
email = models.EmailField('email address', unique=True, max_length = 255)
USERNAME_FIELD = 'username'
REQUIRED_FIELDS = ['email']
For me above code simply solved problems.

Solution :
Check the spelling of your REQUIRED_FIELDS
