Raised NodeNotFoundError

When I deploy the project on herokou server, while migrating, I encountered this error. While in my system, there was no such error and the project was working properly

Traceback (most recent call last):

Where is the problem?

It says what the error is. You have an app called "account" and the migrations for this app is looking for migration 0013_auto_20200828_2241 in 'auth" which is one of django's main migrations.

This probably means in your requirements you are using a different version of django to your local. So your local has the migration and the one you are installing on heroku does not?
