adding information to the QueryKey that is not part of the procedure input
thanks for your insights, greatly appreciated 🙏

calling trpc endpoints from vanilla nextJs api routes
related follow-up question @julius :
when I make a server-side call, and it errors (e.g. because of a zod validation error), I get a
