Return django-rest-swagger with internal server error

Question

I create one API resource, and I decided to use django-rest-swagger for this, and I did all the steps as provided in django-rest-swagger

After I tried the URL http: // localhost: 8000 / docs / and I cannot open and view my APIs. A screenshot of the error is shown below. If anyone came across this before please help me.

Answer 1

The error occurred due to old fields from the database that solved this issue.
