any return type for useLoaderData

[Guria]

Hi. I am recently noted that my Route.useLoaderData() has started to return any type. It happens in all routes.
Unfortunately I don't know when it is started, so I am unable to identify exact change that caused that to happen.
I have a regular setup with vite and plugin and I am sure I had it working in type safe way.

I just checked with freshly set up using create-tsrouter-app and wasn't able to reproduce too.

I have tried to clean cache, reinstall node_modules, double checked plugin is in vite configuration, ensured routeTree.gen.ts is recreating.

I would appreciate any directions for debug as I can't provide a reproduction yet.

I have prepared a minimal repo with reproduction.
I have checked in Github Codespaces to make sure my local environment is not a source of issue.
Please help me debug and find what is going wrong.

the type registration was incorrect:

diff --git a/src/app/entrypoint/providers.tsx b/src/app/entrypoint/providers.tsx
index 5698fef..e5e4775 100644
--- a/src/app/entrypoint/providers.tsx
+++ b/src/app/entrypoint/providers.tsx
@@ -4,7 +4,7 @@ import { createAppRouter } from './router'
 // Register the router instance for type safety
 declare module '@tanstack/react-router' {
        interface Register {

+               router:  ReturnType<typeof createAppRouter>
        }
 }

Thank you! I wonder how that's happened in the first place. Because it was definitely working.

Not sure if this has been addressed or not, but I am still seeing the same thing with react-router.
Here is a small reproduction: https://codesandbox.io/p/sandbox/tanstack-router-useloaderdata-any-lljk6x?file=%2Fsrc%2Fpages%2FGames.tsx%3A16%2C1-17%2C1

sandbox is not public? can you just share a git repo?

My mistake. I changed it to public now.

[schiller-manuel]

you were missing the type registration.

see https://tanstack.com/router/v1/docs/framework/react/api/router/RegisterType

Oh wow, okay. I am clearly bad at reading. Thank you for the response :)

I have similar problem, but in my case it caused by lack of node16 module resolution support (generated file paths in routeTree.gen.ts have no extension). It seems like a few years ago there was the fix, but it's gone now, I guess.

addExtensions still exists in the generator config
