Webflow Form submission with JS enabled

I have integrated Webflow HTML, CSS and JS with my custom code using Python and Django framework , but the form is not sending post request to the server after submitting (Note- the form is working properly with JS disabled).

Here is my site Read-Only: LINK
(how to share your site Read-Only link)

Your setup is a bit impossible to guess-
If you’re using Python and Django, have you exported your site and are hosting it elsewhere?

If so then your form submission setup and handler would be entirely custom.
