How to catch an event webhook from sendgrid.

[Elindo586]

Summary

So I got the code working from the localhost using ngrok http 3000

But when I try it live in Vercel it doesn't work?

Environment variables? <-- I had a problem with that during my local test because the key provided by Sengrid didn't contain the BEGIN PULICK KEY and END PUBLIC KEY part... instead they just gave me a key without the BEGIN AND END PART
myKeyGoesHere <-- this is what they gave me..
-----BEGIN PUBLIC KEY-----\nmyKeyGoesHere\n-----END PUBLIC KEY----- <-- I added this to make it work with ngrok..

So the Vercel environment variable is as in my localhost with BEGIN and END..

But the logs from Vercel is showing this error:

How could I fix it?

the code is here:

I am running node 24.4 in my localhost... the node version in Vercel goes up to 22x... <--- could this be a problem?

So, the documentation from sendgrid uses startkbank-ecdsa as in this link:
https://github.com/sendgrid/sendgrid-nodejs/blob/main/packages/eventwebhook/src/eventwebhook.js

So I changed to code to use starkbank-ecdsa... as shown here:
https://github.com/Elindo586/mcheck/blob/main/app/api/sendgrid-webhook2/route.js

But errors persist:

Could this be a problem? This is how my key looks in Vercel

-----BEGIN PUBLIC KEY-----
\nHereIsTheRestOfMyKeyandstuffxxxx
keepsGoingToNextLineLIkeThis\n-----END PUBLIC KEY-----

^^^ it looks like 3 lines at Vercel environment variables...

while in my local host .env is of course all in one line:
SENDGRID_SECRET="-----BEGIN PUBLIC KEY-----\nHereIsTheRestOfMyKeyandstuffxxxxkeepsGoingToNextLineLIkeThis\n-----END PUBLIC KEY-----"

I found this on Google:

const SENDGRID_SECRET = process.env.SENDGRID_SECRET.replace(/\\n/g, '\n')

Try that 😅 let's see if it does the trick
