Cannot make transition of my Youtube broadcast to live using Youtube API
<p>Right now I'm trying to figure out what i'm doing wrong when making transition of my YT broadcast to live.</p>

<p>So I make the request and get the following response:</p>

<pre><code>{
  "code" : 403,
  "errors" : [ {
    "domain" : "youtube.liveBroadcast",
    "message" : "Invalid transition",
    "reason" : "invalidTransition",
    "extendedHelp" : "https://developers.google.com/youtube/v3/live/docs/liveBroadcasts/transition#params"
  } ],
  "message" : "Invalid transition"
}
</code></pre>

<p>Of course i've read docs many times so I've monitored the LiveStream and was waiting for its "active" state (and my Broadcast has lifeCycleStatus="ready").</p>

<p>Error message doesn't explain real reason why cannot I do the transition.<br>
And... of course I do not have access to logs of Youtube servers :)</p>

<p>What can you suggest?<br>
How to find out where am I wrong?</p>

<p>So even if i've missed something, docs and error message do not help me to understand anything. So anyway it is kind of a "bug" for YT LiveStreaming API...</p>
