While upgrading EC2 servers behind an AWS Elastic Load Balancer (ELB) I noticed that the nginx error log was reporting that my health-check was getting molested. Here is the simple curl test showing the 200 result. The error message, then the solution follow.

$ curl -I localhost/ELB-health-check

If you are updating and older Django project and getting an error in this form:

TypeError: attribute name must be string, not 'bytes'

It's likely that you have existing migrations in your code base that have legacy byte strings. I found them in two places. In the related_name as shown below

('article', models.ForeignKey(related_name=b'author', to='core.Article', on_delete=models.CASCADE, null=True)),
