returning undefined from server gets stripped on the client

I encounter this issue when working with TRPC React under a Turborepo. But I works fine on Next

I see that its been merged but still appearing on my end
https://github.com/trpc/trpc/issues/4049

That ticket is unrelated to what you're showing

React Query adds undefined to the type, because until the query has completed, it's undefined

But this is a react query thing, not to do with tRPC

thanks for replying @Nick Lucas . The point is I need that undefined. How do i fix it on the React app ?

Oh sorry, missed it in the first image

Could you open a GitHub issue? Looks potentially related to react vs next

(But the issue template will collect other possibly related information)
