Webhook controller functionality for customer.subscription.deleted fails

[ghost]

From my testing, it appears that this will fail:

    /**
     * Handle a Stripe webhook call.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Symfony\Component\HttpFoundation\Response
     */
    public function handleWebhook(Request $request)
    {
        ...
        $this->eventExistsOnStripe("customer.subscription.deleted");
    }

It may be related to recent major updates to Stripe's platform (Billing product). Perhaps updating the underlying stripe-php package will help?

This can be fixed by ensuring that you have this in your testing environment's env file:
