Description
I have a custom \Symfony\Component\HttpKernel\DataCollector\DataCollector that collects handled Exceptions to the profiler.
Something like:
public function collect(Request $request, Response $response, ?Throwable $exception = null) : void
{
$this->data = [
'errors' => $this->cloneVar($someException),
];
}But I noticed something odd. It works almost always, except when the exception is thrown from a place that has a null argument passed. In those cases, I would get the following error when viewing the profiler in the /_profiler UI:
I was able to isolate the error and it seems that it's related to the fact that the Symfony WebProfiler serialized the cloned data.
Not sure how this can be resolved.
How to reproduce
<?php
use Symfony\Component\VarDumper\Cloner\VarCloner;
use Symfony\Component\VarDumper\Dumper\HtmlDumper;
include 'vendor/autoload.php';
function throwException($rootValue) {
throw new Exception('This is an exception');
}
try {
throwException(null);
} catch (Exception $exception) {
}
$cloner = new VarCloner();
$cloned = $cloner->cloneVar($exception);
// Serialize and deserialize the cloned var, to simulate what happens
// when this exception is inside a Symfony WebProfiler profile.
$deserialized = unserialize(serialize($cloned));
$dumper = new HtmlDumper();
echo $dumper->dump($deserialized);Output
