Cant sign into my Django project but i can sign up no problem "ValueError at /accounts/login/"

Hey guys I'm just getting an error thrown up at me when I go to sign in on my Django project I was just wondering could anyone help shed some light as to what the error is. Ill include both my views and URLs below. I assume this is where the error must be but I'm unsure so apologies if I have not provided the right code. I will also include my templates. Repost

urls
    from django.urls import path
    from phoneshop import views
    from .views import signupView, signinView, signoutView

    urlpatterns = [
        path('create/', signupView, name='signup'),
        path('login/', signinView, name='signin'),
        path('logout/', signoutView, name='signout'),
    ]


 views
        from django.shortcuts import render, redirect
        from .forms import CustomUserCreationForm
        from .models import CustomUser
        from django.contrib.auth.models import Group
        from django.contrib.auth.forms import AuthenticationForm
        from django.contrib.auth import login, authenticate, logout
        
        def signupView(request):
            if request.method == 'POST':
                form = CustomUserCreationForm(request.POST)
                if form.is_valid():
                    form.save()
                    username = form.cleaned_data.get('username')
                    signup_user = CustomUser.objects.get(username=username)
                    customer_group = Group.objects.get(name='Customer')
                    customer_group.user_set.add(signup_user)
            else:
                form = CustomUserCreationForm()
            return render(request, 'signup.html', {'form':form})
        
        def signinView(request):
            if request.method == 'POST':
                form = AuthenticationForm(data=request.POST)
                if form.is_valid():
                    username = request.POST['username']
                    password = request.POST['password']
                    user = authenticate(username=username, password=password)
                    if user is not None:
                        login(request, user)
                        return redirect('phoneshop:allProdCat')
                    else:
                        return redirect('signup')
                else:
                    form = AuthenticationForm()
                return render(request, 'signin.html', {'form': form})
