Symfony 4 dump function doesn't work properly

Question

I'm developing some REST APIS and the dump function stopped working in my dev env, it doesn't show any information about anything or return the usual output

I tried to debug using the dump() function (from the /vendor/symfony/var-dumper/Resources/functions/dump.php file) and the \Symfony\Component\VarDumper\VarDumper::dump() function with the same results: it doesn't show anything or throw a php exception.

Also, i've tried both: use the regular debug commands (i.e bin/console config:dump-reference) and reinstall the debug-bundle

In this example my program returns a notification: Array to string conversion

$foo = array("asdads", "czxcxzc");
dump($foo);

In this other example the response is null

$foo = "bar";
dump($foo);

I just need the regular output for this function: is really useful to debug and see whats going on with my program

What is exactly your problem ? Can you add some code/examples ? — Jérôme
i've just added some code examples, and tried to be a lil more specific with the problem (srry, kinda noob) — Enrique Nuñez Malledo
Do you have a config/packages/debug.yaml file? if so, please post it — Arleigh Hix

I think that i've figure this out.

The problem was that i've added the __destruct() method on my main controller class (App\Controller)

App\Controller

abstract class Controller implements ContainerAwareInterface
{

use ContainerAwareTrait;
use ControllerTrait;    
...
public function __destruct()
{
   //Some stuffs here
}

I dont know why, but this method avoids loading for some of these debug methods (maybe some other features, but not sure about it)

The solution (for now) was moving this __destruct() method to my app main controller. Now everything works like a charm
