 The following would prevent the *Not enough arguments* exception to be reported, but any other `RuntimeException` would still be reported.
 
 ```php
-public function report(Throwable $exception)
+public function register(Throwable $exception)
 {
-    if ($exception instanceof RuntimeException) {
-        if (Str::contains($exception->getMessage(), ['Not enough arguments'])) {

+    $this->reportable(function (RuntimeException $e) {
+        if (Str::contains($e->getMessage(), ['Not enough arguments'])) {
+            return false;
         }
-    }
-
-    parent::report($exception);

 }

 If you would like to disable the reporting only when running from the built phar file you could use the [`\Phar::running()`](https://php.net/manual/en/phar.running.php) function.
 
 ```php
 if (\Phar::running()) {
-    if ($exception instanceof RuntimeException) {
-        if (Str::contains($exception->getMessage(), ['Not enough arguments'])) {
-            return;

+            return false;
         }
-    }

 }
