sanitizing output based on output schema
As i understand, the
.output will only ensure the schema is respected, but will not sanitize output on the go (even tho it could be possible with a z.strictObject()):
```ts
.output(someSchema) // <- does not sanitize data
// ---...middleware executed twice? should i use `experimental_standaloneMiddleware`?
I'm trying to build something like this:
1. a session middleware which reads request cookie, extract userId and pass in ctx.session
2. a permissions middleware which should pick the userId from the ctx.session and exposes user permission in ctx.session

Is it possible to use tRPC with Deno over Websockets only?
I guess this is NodeJS: import ws from 'ws';
and apply WSSHandler requires it as in the example here:
https://trpc.io/docs/server/websockets

Tprc Tanstack integration types
Hello guys! I wanted to create a reusable query, like this:
export function useProjectBySlug(slug: string, options?: any) {
const queryOptions = trpc.projects.getBySlug.queryOptions({ slug }, options);
return useSuspenseQuery(queryOptions);
} ...Migrating v11 from classic client to TanStack Query: “Error: experimental_prefetchInRender feature ”

But when I call useQuery() on my API, it's returning a rejected promise with the error message "Error: experimental_prefetchInRender feature flag is not enabled". Why does it think I requested a prefetch, and how do I correct the code so it doesn't request a prefetch?
I asked Copilot and got this response:

I tried the onError handler, but its too late at this point. the error is already a TRPC error. I tried using a middleware as well, but the errors throw are not caught by the middleware.
The only reference I've found in the docs is here:...
can't access property Symbol.for("trpc_untypedClient"), client is undefined
