Cannot serve prerendered routes with input params.

[cacalo]

Describe the bug
Edge function crashed when trying to access routes with params (i.e: user/:userId). The crash log says: "Error: Reading or writing files with Edge Functions is not supported yet. Visit https://ntl.fyi/edge-functions-filesystem to learn more and tell us about your use cases for file system access.".
All other routes that not include params, (common routes and child routes without params) work as intended.
This regression breaks my entire site as now users cannot verify their account as it is done by a path with params (path: 'activate/:token').

To Reproduce
Steps to reproduce the behavior:

1. Create a component.
2. Asign it a route with params. (user/:userId). It dosn't matter if you consume the param or if you have withComponentInputBinding(), it always fails.
3. Access the route directly with the url (not using the site's navigation).
4. See error.

Expected behavior
The server should not crash and I should be directed to the component within user:userId.

Versions

• Angular : 19.0.6
• @netlify/angular-runtime: 2.2.1.
• I did not opt-in to the new render engine and I included netlifyCommonEngineHandler() on my server.ts.

Hi @cacalo
Would you be able to create some minimal reproduction for this? In various attempt I do get some errors, but none of my attempts resulted in

Error: Reading or writing files with Edge Functions is not supported yet

errors yet

Just to show what I tried without trying to some very odd things in effort to reproduce - I tried starting from scratch (with ng new) with prerendering enabled and using CommonEngine - and added param path pieh/ntl-ang19-params@80e00c4

https://app.netlify.com/sites/stellular-squirrel-571734/deploys/67864b3d3f13980e91f6f485 was the build for above repo/commit and hitting https://stellular-squirrel-571734.netlify.app/test/dynamic-params-path renders just fine and also being able to grab dynamic part from path ( https://github.com/pieh/ntl-ang19-params/blob/80e00c4e4cec4c1367c0d62c966e35b01f841129/src/app/app.routes.ts#L5 being config for dynamic path test )

I failed to create a minimal reproduction repo. It worked.
I made a new project with App Engine Developer Preview and ported components to it and now it works.
I'm not sure what was broken, but thank you for pointing out that it was my mistake when I was starting to doubt the tool and the drastic changes that Angular is launching.

cacalo I am running into exactly this issue. It's an SSR route that has a route param. I cannot reproduce it locally with netlify dev.

What did you do to solve your version of this issue? I could see the issue being with something I am doing like you say, but this error message gives me nothing to go from.

My callback has deno-fs as the error giver but I dont think the issue is there

Angular v19.1.3
@netlify/angular-runtime v2.2.1

I ended up creating a new project and porting my project to it, as I could not find a way to fix it and I could not reproduce the error on the new project. What was broken? No idea.
