Webhooks and JNOS Filter to extracting data from webhook IFTTT

Folks,
silly thing, I’m using Webhooks in IFTTT with StreamerBot Website, and If Maker Event, then execute a Streamer bot action with arguments from JSON input.

I have a problem to code the filter, I can’t easily retrieve the ‘amount’ and ‘currency’ data from a webhook data format like this from tipo.live:
{
“id”: 3425342,
“status”: “test”,
“name”: “Test Name”,
“message”: “Test Content”,
“paid_at”: “2025-06-20T18:18:27.000000Z”,
“goal”: “next-story”,
“amount”: 900,
“amount_user”: 0,
“currency”: “PLN”,
“payment_method”: null
}

every time I get an error, what Json code to use?

in trigger IFTTT:

for this Action:
