Hands-on Exercise: Webhook-Driven Order Processing System

Describe the problem/error/question

Hi,
I am completing the N8N102 – Order Webhook Processor exercise.
The Academy Webhook Tester sends data to my webhook. When I copy one of the production executions to the editor and use it as pinned data, the webhook body only contains:
{
“order_id”: “ORD-039”,
“customer_id”: “CUST-009”
}
The total field is missing, even though the exercise requires these three fields:
order_id
customer_id
total
Because total is missing, this expression in my InsertOrder Data Table node returns undefined:
{{ $(‘WebhookNewOrder’).item.json.body.total }}
How should I fix this?

is that pinned data from an older execution, possibly captured before a recent fix to the Academy Webhook Tester? There’s been at least one other recent fix to what the tester sends check the N8N102 corrections thread. Try triggering a fresh test run from the Webhook Tester right now and re-copying that execution, if total shows up in a new run but not the old pinned one, it confirms the old capture was just stale data, not something wrong in your workflow.
