Stripe PHP Best way to debug an SignatureVerificationException with Stripe-cli - laravel

Question

I created a webhook to get informations about checkout sessions :
public function stripeWebhookCheckout(Request $request)
{
\Stripe\Stripe::setApiKey(env("STRIPE_SECRET"));
// You can find your endpoint's secret in your webhook settings
$endpoint_secret = 'whsec_fVBkAmCztUTacQKZiyjmcq6QQrl8lKL1';
$payload = #file_get_contents('php://input');
$sig_header = $_SERVER['HTTP_STRIPE_SIGNATURE'];
$event = null;
try {
$event = \Stripe\Webhook::constructEvent(
$payload,
$sig_header,
$endpoint_secret
);
} catch (\UnexpectedValueException $e) {
// Invalid payload
http_response_code(400);
exit();
} catch (\Stripe\Exception\SignatureVerificationException $e) {
// Invalid signature
http_response_code(400);
exit();
}
// Handle the checkout.session.completed event
if ($event->type == 'checkout.session.completed') {
$session = $event->data->object;
// Fulfill the purchase...
handle_checkout_session($session);
$stripeSessionId = $session['id'];
if (isset($stripeSessionId)) {
$payment = Payment::where('stripe_sessioncheckout_id', '=', $stripeSessionId)->first();
$payment->status = "success";
$payment->data = $session;
$payment->save();
}
}
http_response_code(200);
}
I use stripe-cli to test my webhook in local. And i have this kind of result
$ stripe listen --forward-to jvlb.test/api/stripe/webhook/checkout

2019-11-28 16:19:06 <-- [400] GET https://jvlb.test/api/stripe/webhook/checkout [evt_1FjsW5FIYszmshR0eGSB9GDo]
To debug it i changes the http_response_code(400) and I realised it generate a SignatureVerificationException.
My question is, how can i debug this ? Is it the $_SERVER['HTTP_STRIPE_SIGNATURE'] who is wrong ?
Thanks

i found a solution, if it can help people in the future :
I made a mistake in the way i use stripe-cli, i forgot "https://".
The good way is :
stripe listen --forward-to https://jvlb.test/api/stripe/webhook/checkout
And then i had few error of code to manage. I just used the tail command on my log file
tail -f storage/logs/laravel-2019-11-29.log
