everyone. I have views.py here, I want to calculate different status' tasks and output to chart.js pie-chart. I have tried many ways but none of them works. I have an error saying my views def didn't return HttpResponse, can anyone tell me what it is, please? I used template tags in HTML.

Thanks.

views.py

def visualisation(request, project_id):

    project = Project.objects.get(id=project_id)

    counts_data = Todo.objects.annotate(
        to_do_count = Count('id', filter=Q(status='to_do')),
        in_progress_count = Count('id', filter=Q(status='in_progress')),
        done_count = Count('id', filter=Q(status='done'))
        ).order_by('-to_do_count')

    context = {'counts_data', counts_data}
    return render(request, 'todo_lists/progress.html', context)

html

    data: {
        labels: [1,2,3],
        
        datasets: [{
            label: '# of Votes',

            data:[{% for todo in counts_data %} {{ todo }}, {% endfor %}],,
            
            backgroundColor: [
                'rgba(255, 99, 132, 0.2)',
                'rgba(54, 162, 235, 0.2)',
                'rgba(255, 206, 86, 0.2)'
            ],
            borderColor: [
                'rgba(255, 99, 132, 1)',
                'rgba(54, 162, 235, 1)',
                'rgba(255, 206, 86, 1)'
