How do I log thrown errors from the query/ mutation on the server side globally?

I was surprised to find that the server servicing tRPC requests do not log any thrown errors from a query / mutation to the console by default (but the client does capture errors). I want to be able to log all errors on the server side. How would I do this? This page doesn't really give me any clues as I don't know what trpcNext.createNextApiHandler refers to: https://trpc.io/docs/server/error-handling#handling-errors I am using the express adapter with tRPC. I do not want to have to attach an error handling function to each query / mutation I define.

All the adapters have an onError callback so you can use that Look at the docs for your adapter

It doesn't offer anything around that: https://trpc.io/docs/server/adapters/express Same with the source for it: https://github.com/trpc/trpc/blob/main/examples/express-server/src/server.ts

It might not be directly documented in this case, but it’s there and your editor autocomplete is all the docs you really need, get your editor to list all the options you can pass to the adapter

Typing on did help in the autocomplete for the adapter, thanks 
    trpcExpress.createExpressMiddleware({
      router: appRouter,
      createContext,
      onError({ error, ctx }) {

      },
    trpcExpress.createExpressMiddleware({
      router: appRouter,
      createContext,
      onError({ error, ctx }) {

      },
