Typescript type error with latest version

I'm initialising a project with trpc v11 and I'm trying to strictly follow the documentation for react-query.

I face a problem: everything works fine at runtime but in vscode I have 2 typescript errors:

1/ My hello procedure get this type error on 
useQuery
 : Property 'useQuery' does not exist on type 'never'.ts(2339) on this line const q = trpc.hello.useQuery("thing"); in my component.

2/ In the 
AppRouter
 in the frontend on this line:
export const trpc = createTRPCReact<AppRouter>();

Truncated error (full: https://pastebin.com/ZDD5nsy3): 
Type 'CreateRouterInner<RootConfig<{ ctx: object; meta: object; errorShape: DefaultErrorShape; transformer: DefaultDataTransformer; }>, { hello: BuildProcedure<...>; }>' does not satisfy the constraint 'Router<any, any>'.

              Type '"UNSUPPORTED_MEDIA_TYPE"' is not assignable to type '"INTERNAL_SERVER_ERROR" | "PARSE_ERROR" | ... few more ... | "CLIENT_CLOSED_REQUEST"'.ts(2344)


Context:
I'm using react + vite + react query + bun.
package.json of frontend & backend are matching to 11.0.0-rc.340
