I get this error after running migrate. I'm not sure why it gets thrown but the migration actually goes through. Double check your cassandra keyspace and see if your column families have been created corretly despite this error.

Thanks man .

I'm going to keep this issue open since it is a bug; but I'm going to update the title to more accurately reflect the issue.

This happens when Django is trying to generate the final output after the migrate command finishes successfully.
