Debug an issue on vercel

Help
1

Hello,

Having never used Vercel before. I have deployed a personal project which is build on Next JS 15, and uses Postmark to handle form delivery.

Expected behavior

When the visitor fills in the form on /contact page, the message is sent to Postmark

Code, configuration, and steps that reproduce this issue

Visitor fills in form and presses the send button. Either a success or error message appears. Currently I see a success message. But I do not see the message appear in Postmark.

Issue
I’d just like some pointers for how I might debug the issue?

If you’re sending messages using Postmark API and the message doesn’t appear at all in Postmark’s Activity, it means it was never accepted for sending. You would need to reference your own logs to review the response code they sent to you when you submitted the message request.

@grant5 Welcome to the Vercel community.

You can try Postman to verify the form submission from Postmark.

Ref: Postman

Try sending the request and see what error you are getting. It will help you in determining the exact issue.
