cant change language using {% url 'set_language' %} in Django translation - django

Question

this was actually working fine i don't know what changed or happened.
suddenly {{ redirect_to }} as shown here from django documentation
<input name="next" type="hidden" value="{{ redirect_to }}">
doesn't have a value when i view it from developer tools
this my template code
{% load i18n %}
{% get_current_language as LANGUAGE_CODE %}
{% get_available_languages as LANGUAGES %}
{% get_language_info_list for LANGUAGES as languages %}
<li class="mx-0 mx-lg-1">
<form action="{% url 'set_language' %}" method="post" id="lang_form" style="display: flex; margin-top: 1rem;">{% csrf_token %}
<input name="next" type="hidden" value="{{ redirect_to }}">
<select id="language_selection" onchange="ChangeLanguage(this);" class="form-control bg-primary text-white" name="language">
{% for language in languages %}
<option class="text-white" value="{{ language.code }}"{% if language.code == LANGUAGE_CODE %} selected{% endif %}>
{{ language.name_local }}
</option>
{% endfor %}
</select>
</form>
</li>
the form is submitted using this java script code
function ChangeLanguage(element){
const lang_form = document.getElementById('lang_form');
console.log(lang_form);
lang_form.submit();
}
and this is my main urls.py
rom django.contrib import admin
from django.urls import path, include
from django.conf import settings #add this
from django.conf.urls.static import static #add this
from django.contrib.auth import views as auth_views
