TemplateDoesNotExist at /product/1/ productDetail.html

I am making an about page for every item. There is a problem that occurred when I am pressing 'View' on my store page: TemplateDoesNotExist at /product/1/ productDetail.html

I have tried specifying the directory by putting {{% extends store/main.html %}}, it did not help. Please assist me.

    path('product/<int:pk>/delete-comment', views.delete_comment, name='delete-comment'),

]

why am I getting this error, if productDetail exists?

return render(request, 'productDetail.html', context)

return render(request, 'store/productDetail.html', context)
