Django Recaptcha fails the form validation - django

Question

I'm implementing RecaptchaV3 on a Django application.
I am currently following this github(https://github.com/kbytesys/django-recaptcha3) README text to set it up.
I have a feedback form that sends an email with the subject and text.
However, when I add RecaptchaField in django form, the POST request no longer passes the form.is_valid() in views.py.
Does anyone have a thought/fix on how to overcome this problem?
Thank you in advance
forms.py
class contactForm(forms.Form):
name = forms.CharField(max_length=50, required=True, widget=forms.TextInput(attrs={'placeholder': 'Name (required)'}))
email = forms.EmailField(max_length=100, required=True, widget=forms.TextInput(attrs={'placeholder': 'Email (required)'}))
subject = forms.CharField(max_length=200, widget=forms.TextInput(attrs={'placeholder': 'Subject'}))
message= forms.CharField(max_length=1000, widget=forms.Textarea(attrs={'placeholder': 'Message'}))
captcha = ReCaptchaField()
views.py
def homepage(request):
form = contactForm()
if request.method == 'POST':
form = contactForm(request.POST)
if form.is_valid():
print("form is valid")
form = contactForm()
return render(request, 'homepage/home.html', {'form':form, 'context':context,})
template
<form class="form-horizontal" id="contactForm" method="POST" action="?">
{% csrf_token %}
<div class="form-group">
<div class="form-group">
<label for="name">Your Name (required)</label><br>
{{ form.name }}
</div>
<div class="form-group">
<label for="email">Your Email (required)</label><br>
{{ form.email }}
</div>
<div class="form-group">
<label for="subject">Subject</label><br>
{{ form.subject }}
</div>
<div class="form-group">
<label for="message">Your Message</label><br>
{{ form.message }}
</div>
</div>
<button class="btn" type="submit">SEND</button>
</form>
in the header, i've added
{% recaptcha_init %}
{% recaptcha_ready action_name='Homepage' %}
