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

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()

getFoo()

I am expecting the errorFormatter to be called and transform the error to

{ message: 'Huge error' }

{ message: 'Huge error' }

, but when using the

appRouter.createCaller()

appRouter.createCaller()

, the

errorFormatter

errorFormatter

is never called.

Any idea what I am missing?
