Error setting contentDetails for live event - Youtube Live API v3 - api

Question

I've been using php to create yt live events successfully for a while. Since I've tried to disable embedding I've received the following error:
["Error calling POST https:\/\/www.googleapis.com\/youtube\/v3\/liveBroadcasts?part=snippet%2Cstatus: (400) contentDetails"]
The code is as follows:
$client = new Google_Client();
$client->setClientId($OAUTH2_CLIENT_ID);
$client->setClientSecret($OAUTH2_CLIENT_SECRET);
$client->refreshToken($tokens[0]['google_oauth_refresh_token']);
// Define an object that will be used to make all API requests.
$youtube = new Google_Service_YouTube($client);
// Check to ensure that the access token was successfully acquired.
if ($client->getAccessToken()) {
// die();
// Create an object for the liveBroadcast resource's snippet. Specify values
// for the snippet's title, scheduled start time, and scheduled end time.
$broadcastSnippet = new Google_Service_YouTube_LiveBroadcastSnippet();
$broadcastSnippet->setTitle($_POST['title']);
$broadcastSnippet->setDescription($_POST['description']);
$broadcastSnippet->setScheduledStartTime(date('c', strtotime($_POST['start_date']))); //'2034-01-30T00:00:00.000Z');
$broadcastSnippet->setScheduledEndTime(date('c', strtotime($_POST['start_time']))); // '2034-01-31T00:00:00.000Z');
$contentDetails = new Google_Service_YouTube_LiveBroadcastContentDetails();
$contentDetails->setEnableEmbed(false);
// debug($contentDetails);
// Create an object for the liveBroadcast resource's status, and set the
// broadcast's status to "private".
$status = new Google_Service_YouTube_LiveBroadcastStatus();
// $status->setPrivacyStatus('public');
$status->setPrivacyStatus('private');
// $status->setPrivacyStatus('unlisted');
// Create the API request that inserts the liveBroadcast resource.
$broadcastInsert = new Google_Service_YouTube_LiveBroadcast();
$broadcastInsert->setContentDetails($contentDetails);
$broadcastInsert->setSnippet($broadcastSnippet);
$broadcastInsert->setStatus($status);
$broadcastInsert->setKind('youtube#liveBroadcast');
// Execute the request and return an object that contains information
// about the new broadcast.
$broadcastsResponse = $youtube->liveBroadcasts->insert('snippet,status', $broadcastInsert, array());
// Create an object for the liveStream resource's snippet. Specify a value
// for the snippet's title.
$streamSnippet = new Google_Service_YouTube_LiveStreamSnippet();
$streamSnippet->setTitle('Transcoder - '.$_POST['title']);
// Create an object for content distribution network details for the live
// stream and specify the stream's format and ingestion type.
$cdn = new Google_Service_YouTube_CdnSettings();
$cdn->setFormat("720p");
$cdn->setIngestionType('rtmp');
// Create the API request that inserts the liveStream resource.
$streamInsert = new Google_Service_YouTube_LiveStream();
$streamInsert->setSnippet($streamSnippet);
$streamInsert->setCdn($cdn);
$streamInsert->setKind('youtube#liveStream');
// Execute the request and return an object that contains information
// about the new stream.
$streamsResponse = $youtube->liveStreams->insert('snippet,cdn',
$streamInsert, array());
// debug($streamsResponse);
// Bind the broadcast to the live stream.
$bindBroadcastResponse = $youtube->liveBroadcasts->bind(
$broadcastsResponse['id'],'id,contentDetails',
array(
'streamId' => $streamsResponse['id'],
));

Answer 1

In this line:
$broadcastsResponse = $youtube->liveBroadcasts->insert('snippet,status', $broadcastInsert, array());
It should be:
$broadcastsResponse = $youtube->liveBroadcasts->insert('snippet,status,contentDetails', $broadcastInsert, array());
You are setting contentDetails's embedded property but not including it in the request.
If you read the error, that's what it was complaining.
