errorHandler

[Klabauterman]

I am using typescript and I am seeing the errorHandler as required, but I think it should be optional:

app.use(
  authMiddleWare.authn(admin.auth(), {
    attachUserTo: "token",
    errorHandler: () => {
      functions.logger.log("INVALID AUTHENTICATION");
    },
  })
);

So if I want to pass in attachUserTo I must pass in errorHandler as well.

Furthermore I don't really get, how it can be used. In the source code, I see:

if (errorHandler) {
      // Set status onto object too so that user's error handler can have access to it
      resObj.status = status;
      errorHandler(resObj);
    }

resObj seems to be not defined and I think the request and response should be passed as parameters as well to implement something useful with it.
