I can't reproduce. Or am I misunderstand something?

Add error to the controller.

--- a/app/Controllers/Home.php
+++ b/app/Controllers/Home.php
@@ -6,6 +6,6 @@ class Home extends BaseController
 {
     public function index()
     {
-        return view('welcome_message');
+        return view('welcome_message')
     }
 }

$ php spark serve

Navigate http://localhost:8080.

See the log:

If you want to see all errors, you have to change the Boot file: https://github.com/codeigniter4/CodeIgniter4/blob/0406780029a8f0e14fedb2eb6ac2aeda7b87f128/app/Config/Boot/production.php#L11

error_reporting(E_ALL);

Regret the delay, if I received a notification it was lost among all the other notifications.

I downloaded the latest CI4 Ver: 4.1.5 and noticed that the app/Config/Boot/production.php no longer has error_reporting(0)? I unsuccessfully searched for the Change Log update and could not find it?

Anyway my beef was that Production error_reporting used to be set to ZERO and the suggestion was to use CU_DEBUG to select PHP default error_logging by using the following changes, notified in the forum Request:

https://forum.codeigniter.com/thread-80546.html

I have just tested the following proposal :

system/Debug/Exceptions -> public function initialize()
    {
      if( CI_DEBUG )  {  
        set_exception_handler([$this, 'exceptionHandler']);
        set_error_handler([$this, 'errorHandler']);
        register_shutdown_function([$this, 'shutdownHandler']);
      }//endif;  
    }

A memory saving spin-off of using the above was appreciable:

.env 
  # DEFAULT production
  # CI_ENVIRONMENT = production
    # production  ==> 741,720 bytes - memory_get_usage()   
    # production  ==> 746,424 bytes - memory_get_peak_usage()
  # CI_ENVIRONMENT = development
    # development ==> 831,792 bytes - memory_get_usage()
    # development ==> 836,496 bytes - memory_get_peak_usage()

app/Config/Boot/production.php was never changed with regard to the error_reporting() mask. https://github.com/codeigniter4/CodeIgniter4/blob/8c7f70188e2bb7f19e6c7fcbbadb4dcb94c1cbc7/app/Config/Boot/production.php#L11

So it was never error_reporting(0); to begin with.
