Description

I tried to migrate from CommonEngine to AngularNodeAppEngine.

1. The CommonEngine build completes without any errors.

Prerendered 1 static route.
Application bundle generation complete. [121.080 seconds] - 2026-09-23T06:59:53.658Z

Output location: C:\angular\frontend\dist\project

2. I made the needed changes (removed CommonEngine) to the server.ts -file -> ng build -> I got this error message.

3. Tested with angular default server.ts file (same server.ts file that is generated with "ng new new-project --ssr" -command -> Same error
4. Tested with empty server routes -> same error.

export const ROUTES_SERVER: ServerRoute[] = [
];

I'm sorry, but we can't reproduce the problem following the instructions you provided. Can you setup a minimal repro please?

You can read here why this is needed. A good way to make a minimal repro is to create a new app via ng new repro-app and adding the minimum possible code to show the problem. Then you can push this repository to github and link it here.

This might be related to your directory structure so its really important to get an accurate repro to diagnose this.

Project is quite complex and code base is pretty large 😐 Removing all the irrelevant parts just takes too much time / It's might be really hard to pin point the problem since error message is too generic.

I suspected that there might be something wrong with the routes but I got same result with empty routes ([])

So my suggestion is that we wait and see if anyone else has the same problem.

Closing as without a reproduction this is not actionable from our end. Feel free to re-open when there is an actionable reproduction.
