how to redirect on server error ?

[HananoshikaYomaru]

let me describe what I want to do. I have a specific type of error (called it ZError) which could thrown deep inside the code, so sometimes it is uncaught. I want to handle it in the outer most layer. If it is ZError , redirect the user to a specific page. How can I achieve something like this without wrapping every loader with a try catch?

How about using a wrapper function that wraps the process that might throw a ZError with a try...catch, and if a ZError is caught, redirects accordingly?
Instead of calling the process that might throw the error directly within the loader, I think you can write it more simply by passing arguments or executing it through a wrapper function.
