ERROR: Can’t get data for expression under ‘Values to Set > String’ field

Hello, I resolved the issue.

$('Webhook').item.json.body.notifyTravelParty → This doesn’t work.
$('Webhook').first().json.body.notifyTravelParty → This works.

I still don’t understand the error message and why this happens – I think I used the first version, but this might be different.
