Why does an error occur when trying to deploy to dokku?

Question

Django

Hello!
I'm trying to deploy a site using dokku, when I run collectstatic --noinput I get a strange error.
The site is deployed on another server, also via dokku, everything is ok there.
If I turn off collectstatic, the same error appears on the next step -----> Running post-compile hook.
-----> $ python manage.py collectstatic --noinput

See traceback above for details.
You may need to update application code to resolve this error.
Or, you can disable collectstatic for this application:
$ heroku config:set DISABLE_COLLECTSTATIC=1

The problem here is not static.
Updating the django-autocomplete-light package should help you.
