whatsapp automation - verifying meta's webhook

Hey Guys,

I have been struggling getting whatsapp business working. I cant get the webhook working that would do the verification for meta to start using whatsapp business. (it is a silly problem really): I cant get the webhook to return test123, instead it returns {"directResponse":{"directResponse":"test123"}}

I have been debugging for an hour with 4o and it keeps going circles.

I guess anybody here who has built a working whatsapp tool had solved this, so would appreciate if you could share the right way to handle this.

here is my json:

{

"name": "Whatsapp webhook verification",

"nodes": [

{

"parameters": {

"responseMode": "responseNode",

{

"jsCode": "// Get the query parameters\nconst query = items[0].json.query;\n\n// Check if it is a verification request\nif (query && query[\"hub.mode\"] === \"subscribe\" && query[\"hub.verify_token\"] === \"test\") {\n return [\n {\n json: {\n challenge: query[\"hub.challenge\"]\n }\n }\n ];\n}\n\n// Not a verification request\nreturn [\n {\n json: {\n message: \"Not a verification request\"\n }\n }\n];"
