Global ServerFn Middleware to Purge Error Message

[Palmik]

Is it possible to set-up a global ServerFn middleware to purge message from any server-side errors? I would like to do this as a paranoid precaution in case there is some sensitive information in some of the error messages (this might be exposed through a 3rd party dependency as well).

Stack trace is already stripped automatically, it seems.

EDIT: This is possible with global middlware. Global middleware does not work after "devinxi" unless you import the file somewhere, e.g. in router.ts.

@Palmik hello! I'm trying to implement this but is not working. Whenever I throw an error in any function the global middleware is not catching it .
Is there any specific thing to know here?

ok sorry for anyone wondering.. if you create a middleware with type function is working fine:
import { logServerError } from "@/lib/error-logger";
import { createMiddleware } from "@tanstack/react-start";

export const errorLoggingMiddleware = createMiddleware({
type: "function",
}).server(async ({ next }) => {
try {
const response = await next();
if ("error" in response && response.error) {
throw response.error;
}
return response;
} catch (error) {
logServerError(error);
throw error;
}
});
