Incorrect pushSubscription.getKeys method in sample code

[j1mr10rd4n]

The sample code in the Send a subscription to your server section contains the following snippet:

const subscriptionObject = {
  endpoint: pushSubscription.endpoint,
  keys: {
    p256dh: pushSubscription.getKeys('p256dh'),
    auth: pushSubscription.getKeys('auth')
  }
};

However, there is no getKeys method on PushSubscription. The correct method call is getKey(name)
