+(4) Optional: set application `RUNNING_IN_CONSOLE` (highly recommended)
+
+Some Laravel service providers only register their commands if the application is being accessed through the command line (Artisan). Because we are calling Laravel scheduler from a HTTP call, that means some commands may never register, such as the Laravel Scout command:
+
+```php
+/**
+ * Bootstrap any application services.
+ *
+ * @return void
+ */
+public function boot()
+{
+    if ($this->app->runningInConsole()) {
+        $this->commands([
+            FlushCommand::class,
+            ImportCommand::class,
+            IndexCommand::class,
+            DeleteIndexCommand::class,
+        ]);
+
+        $this->publishes([
+            __DIR__.'/../config/scout.php' => $this->app['path.config'].DIRECTORY_SEPARATOR.'scout.php',
+        ]);
+    }
+}
+```
+
+To circumvent this, please add the following to `public/index.php`
+
+```diff

 # Cloud Scheduler Example
 
 Here is an example job that will run `php artisan schedule:run` every minute.
