Invalid X-Forwarded-Port for NextJS deployed application

I have created a NextJS application aws-clerk-nextjs-production.up.railway.app. Logging the x-forwarded-port in the console it seems that instead of either a 443,80 or a 443 value we probably get the value of latest node from the route path.

{
origin: null,
host: 'aws-clerk-nextjs-production.up.railway.app',
forwardedPort: '80',
forwardedHost: 'aws-clerk-nextjs-production.up.railway.app',
forwardedProto: 'https,http',
referrer: null,
userAgent: 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/113.0.0.0 Safari/537.36'
}

{
origin: null,
host: 'aws-clerk-nextjs-production.up.railway.app',
forwardedPort: '80',
forwardedHost: 'aws-clerk-nextjs-production.up.railway.app',
forwardedProto: 'https,http',
referrer: null,
userAgent: 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/113.0.0.0 Safari/537.36'
}

The same application deployed in a AWS Amplify Hosting we get both forwardedPort: '443,80', so i guest it's related to how the headers between nodes of the network are propagated and how it's being merged. Is there a more official way to file a bug report? Do you need more details? Is there a guide i should take a look and improve this report?

an X-Forwarded-Port simply does not exist https://utilities.up.railway.app/raw

thread doesn't actually get closed fwiw but my answer still stands

@brody It may be related to the application/framework. I am using NextJS. How do you retrieve the values from the headers in https://utilities.up.railway.app/raw ? Do you use any framework?

Brody•2y ago

it's just a display of the raw http request it's just there to demonstrate everything that's available to your app on an incoming request and as you can see, no x-forwarded-port header

I will take a better look about how this header is being populated in my case and come back with more information. Thank you for the immediate response and the info 😄
