Failed Step

Set Customer Email — step 2 of 3

▲

What Happened

The expression `{{ $json.customer.email }}` returned undefined. The Webhook node wraps POST body data under `$json.body`, so the path the Set node is checking does not exist at that level.

◆

Primary Cause

`$json.customer` is undefined because the incoming data lives at `$json.body.customer`. The Set node is one path segment too shallow.

🔧

How to Fix

  1. Change the expression from `{{ $json.customer.email }}` to `{{ $json.body.customer.email }}`.
  2. Alternatively, enable "Raw body" in the Webhook node to skip the wrapper and access `$json.customer.email` directly.
