Stripe subscriptions checkout.session.completed resource missing error of invalid_request_error type

I am trying to understand why webhook for checkout.session.completed is crashing when testing it locally with the Stripe CLI. I am using djstripe. My webhook for customer.subscription.created is successful. With the CLI, I am getting the following error with the stripe trigger checkout.session.completed command:

Request failed, status=404, body={
  "error": {
    "code": "resource_missing",
    "doc_url": "https://stripe.com/docs/error-codes/resource-missing",
    "message": "No such payment_page: 'ppage_1Il33eAyVjQjzOsRERzYQSbK'",
    "param": "payment_page",
    "type": "invalid_request_error"
  }

Is the problem with the success url routing? views.py

def create_checkout_session(request):
    """Create a checkout session for Stripe."""
    data = json.loads(request.body)
    priceId = data.get("priceId")
    if not Price.objects.filter(id=priceId).exists():
        messages.add_message(request, messages.ERROR,
                             "That plan price is not available. Please contact support for help.", )
        return HttpResponseRedirect(reverse("users:index"))
    request.account = OrgMembership.objects.filter(my_identity=request.user).first()
    sessionId = stripegateway.create_checkout_session(priceId, request)
    return JsonResponse({"sessionId": sessionId})

The commented out section is original code used and then tried alternative in efforts to try to fix the problem. Any guidance is much appreciated.
