Can you try on v6.0.1 please ?

[MetalCar]

I have the same problem on v6.0.1. In tmp.json is my data stored that I get from the following

registration.pushManager.subscribe(options).then((subscriptionResponse) => {
    // do something with subscriptionResponse...
});

This is my server PHP test file.

$publicKey = trim(file_get_contents('./public_key.txt'));
$privateKey = trim(file_get_contents('./private_key.txt'));

$subscriptionInfo = json_decode(file_get_contents('tmp.json'), true);

$auth = [
    'VAPID' => [
        'subject' => 'mailto:[email protected]', // can be a mailto: or your website address
        'publicKey' => $publicKey, // (recommended) uncompressed public key P-256 encoded in Base64-URL
        'privateKey' => $privateKey, // (recommended) in fact the secret multiplier of the private key encoded in Base64-URL
        'pemFile' => __DIR__ . '/private_key.pem',
    ],
];

$notification = [
    'subscription' => Subscription::create([
        "endpoint" => $subscriptionInfo['endpoint'],
        "keys" => [
            'p256dh' => $subscriptionInfo["keys"]["p256dh"],
            'auth' => $subscriptionInfo["keys"]["auth"]
        ],
    ]),
    'payload' => null,
];

$webPush = new WebPush($auth);
$webPush->setReuseVAPIDHeaders(true);
$report = $webPush->sendOneNotification(
    $notification['subscription'],
    $notification['payload'] // optional (defaults null)
);

I was playing around with this last week, and somehow managed to get it working. Think I just removed the 'pemFile' entry from the VAPID auth array.

Not sure how this solved it or if there will be problems going forward, but for now it is working. Been getting my notifications properly since.

@emerysteele Thanks for your help. I don't know, if this workaround triggers some unexpected behavoir that we don't see yet, but for now it works.
