Hello Spatie team, I am using your package and really find it great, it works perfectly in laravel 6 , When I run from server client gives below error, all of my webhook calls throw this error, that is why I am a bit puzzled, what does this mean? How could I fix it? Missing something?

You're encountering PHP 7.4's typed properties. In my case, I received this error because my job to handle the webhook had a construct method that did not appropriately set the webhookcall property (which must have a type of "Spatie\WebhookClient\Models\WebhookCall").

Here's a proper contruct method:

public WebhookCall $webhookCall;`

public function __construct(WebhookCall $webhookCall)
{
    $this->webhookCall = $webhookCall;
}

Or, you can delete your contruct method to allow it to inherit it from the abstract class.
