Error: Undefined constant "CodeIgniter\CLI\STDERR"

I don't recommend to use CLI command via web.
But If you really want to run it, try:

Code:

--- a/system/CLI/CLI.php
+++ b/system/CLI/CLI.php
@@ -180,6 +180,7 @@ class CLI
            // we need to define STDOUT ourselves
            // For "! defined('STDOUT')" see: https://github.com/codeigniter4/CodeIgniter4/issues/7047
            define('STDOUT', 'php://output'); // @codeCoverageIgnore
+            define('STDERR', 'php://output');
        }
    }
