i know it is an old post, but i have a problem which is related.

I can create a broadcast and bind it the a stream, that works just fine. I have set enableAutoStart to true and"monitorStream": {"enableMonitorStream": False} If I start sending data to that stream after I created the broadcast, the broadcast advances and starts just fine.

The problem is if i am already sending data to that stream before i created the broadcast, it never advances.

The broadcast status is stuck on ready. The Stream status is active

If i try to manually advance the broadcast to tesing or live it fails Encountered 403 Forbidden with reason "invalidTransition"

Is it simply not possible to auto-start a broadcast if data is already sent to it or is there a way to get the broadcast to go live even if data is sent to the stream before the broadcast was created?

Changing to "monitorStream": {"enableMonitorStream": True} had no effect.
