title: Changes to the default error handler mechanism
pull_requests: [18810]

---

Worlds can now have different default error handlers, so there no longer is a global handler.

Replace uses of GLOBAL_ERROR_HANDLER with App's .set_error_handler(handler). For worlds that do not directly belong to an App/SubApp, insert the DefaultErrorHandler(handler) resource.
