wsgi error caused by strange referer

I have deployed my Django application with apache2.4 to my production server. Everything is working fine on my web page but the apache2/error.log is full of these kind of messages:

[Sun Jan 12 14:58:59.308773 2020] [wsgi:error] [pid 13667] [client] mod_wsgi (pid=13667): Exception occurred processing WSGI script '/var/www/html/****/'., referer:
[Sun Jan 12 14:58:59.309501 2020] [wsgi:error] [pid 13667] [client] Traceback (most recent call last):, referer:

[Sun Jan 12 14:58:59.309585 2020] [wsgi:error] [pid 13667] [client] ModuleNotFoundError: No module named 'django', referer:

Does these error messages come from an invalid request to my web server, or is there a real problem with my wsgi setup?

Are these messages ongoing? Because they for sure imply that your code isn’t running, because it doesn’t have access to django (or its virtualenv). If you website is working fine … have you accidentally put in duplicate configurations for your Django site?
