title: Google App Scrtipt | Calendar API - Invalid conference type value
body: <p>So my script - which always worked now broke with the following Error message when trying to insert event to a calendar:</p>
  
  <blockquote>
    <p>Beim API-Aufruf von "calendar.events.insert" ist dieser Fehler aufgetreten: Invalid conference type value.</p>
  </blockquote>
  
  <p>That means that the conferenceTypeValue isnt correct. Here is the json for the calendar event:</p>
  
  <pre><code>"conferenceData": {
        "createRequest": {
          "conferenceSolutionKey": { "type": "eventNamedHangout" },
          "requestId": Utilities.getUuid()
        }
  }
  </code></pre>
  
  <p>Is that a problem with the API? Because in the <a href="https://developers.google.com/calendar/v3/reference/events#resource" rel="nofollow noreferrer">docs</a> it is a right value.</p>
