errorFormatter ignored when using appRouter.createCaller

My errorFormatter works correctly in the actual application using an adapter, e.g.

 trpcExpress.createExpressMiddleware({
                router: appRouter,
                createContext: createTRPCContextFromExpress,
            }),

 trpcExpress.createExpressMiddleware({
                router: appRouter,
                createContext: createTRPCContextFromExpress,
            }),

But in my tests where I just use createCaller, the errorFormatter is never called. I created a quick sandbox to show this behavior: https://stackblitz.com/edit/trpc-server-inferred-type-cannot-be-named-x2pseq?file=src/index.ts When calling getFoo() I am expecting the errorFormatter to be called and transform the error to { message: 'Huge error' }, but when using the appRouter.createCaller(), the errorFormatter is never called. Any idea what I am missing?

Could you open a GitHub issue for this? It might be intentional but I agree it’s illogical as a user Since you have a reproduction case already we can investigate 🙂
