The expression return $this->gateway->webhookTesting()->sampleNotification(constant(Braintree\WebhookNotification::class . '::' . $type), sha1(time())) returns the type Braintree\Webhook which is incompatible with the type-hinted return array.

            constant(WebhookNotification::class .'::'. $type),

It seems like print_r($webhookNotification) can also be of type true; however, parameter $message of error_log() does only seem to accept string, maybe add an additional type check?
