Nested Proxy

Why This Error Occurred

You are defining a Proxy file in a location different from <root>/proxy, which is not allowed.

While in beta, a Proxy file under specific pages would only be executed when pages below its declaration were matched, allowing nesting Proxy files. Based on customer feedback, we have replaced this API with a single root Proxy.

Possible Ways to Fix It

Declare your Proxy in the root folder and use NextRequest parsed URL to define which path the Proxy should be executed for.

For example, a Proxy at pages/about/_proxy.ts can move the logic to <root>/proxy.ts in the root of your repository. Then, a conditional statement can be used to only run the Proxy when it matches the about/* path:

import type { NextRequest } from 'next/server'

export function proxy(request: NextRequest) {
  if (request.nextUrl.pathname.startsWith('/about')) {
    // This logic is only applied to /about
  }

  if (request.nextUrl.pathname.startsWith('/dashboard')) {
    // This logic is only applied to /dashboard
  }
}

If you have more than one Proxy, you should combine them into a single file and model their execution depending on the incoming request.
