`FST_ERR_REP_ALREADY_SENT` when using `res.send()`

I've setup context as such: ```typescript import { CreateFastifyContextOptions } from '@trpc/server/adapters/fastify'; import models from '../database/models.js'; ...

"Invalid Hook Call" with minimal example

I am getting react invalid hook call errors when trying to add the tRPC react query integration to a project. I am still scaffolding the project, so it isn't much more complicated than a minimal example. The only weird thing I am doing is trying to use deno. I started with one of the vite react templates (I think it was a deno based template, but it was based on deno v1 so I had to make a few small adjustments). It has a barebones hono server hosting tRPC with an adapter. All I am trying to do right now is follow the guide for adding the trpc and react query providers to App.tsx. ```...

Error: Error serializing `.trpcState.json.queries[3].promise` returned from `getStaticProps`

Hello! Doing a migration from v10 to v11 in T3 based app. It worth to mention that the same code works with no issues on v10. Migration process went pretty well and I'm able to run the app localy. However during build I'm start facing such errors (pic 1) I'm trying to debug that, but surprisingly that happens not every build. (pic2) I'm using pretty standart setup and don't see any reasons that may cause that in change logs. (pic3)...

trpc 11 superjson transformer not working with unstable_httpBatchStreamLink

Hello! I have been using httpBatchLink for quite a while but wanted to swap to unstable_httpBatchStreamLink. However, I noticed that any procedure returning a Map isn't being converted correctly. It is only an issue when using unstable_httpBatchStreamLink. Is this a known issue?

Throw NOT_FOUND on nullish

I have many procedures like this: getFoo: protectedProcedure.query(({ input }) => db.foo.findFirst({ id: input.id }) This example uses Drizzle, which doesn't have a findFirstOrThrow convenience function. Since i want to throw TRPCError when the DB record couldn't be found, i'd have to write this code everywhere:```ts getFoo: protectedProcedure.query(async ({ input }) => {...

How can i check if an error is a TRPC Error in the browser?

error.message // NOT_FOUND (throwing this intentionally - i'd like to build a react error boundary that has specific handling for TRPC Errors like NOT_FOUND)
Object.getPrototypeOf(error) // default "Error" object/class
error instanceof TRPCClientError // false. this would have been my best bet.
