Vercel Proxy server Got 502 Bad Gateway

Help
1

Hello, there are error 502 status code when we trying to implement vercel rewrite proxy API url to another Backend API URL

For example:
vercel react.js app domain: app.example.com
Backend API that we rewrite url:
api.another-domain.com/api/v1/ rewrites to app.example.com/api/v1

After we check our logs inside Backend API APM monitoring. there is no error such 502 status codes.

But, when we inspect in vercel runtime logs. it state 502 error code

Is there anyone know which 502 comes from ?
And can we debug more deep for specific log by its requestId. i can’t find page that i can use to deep check specific log. so it always stuck when we debugging with less knowledge of log :slight_smile:
