/push/startup always succeeds even if an invalid rtmpURL is specified

Hello.
I use /push/startup api for youtube streaming.
The startup restapi call always succeeds, even if an invalid rtmpURL is specified.

3. Symptoms

1) The startup api succeeds even if you use the the wrong stream key value ("u12321233rk5e-f7uv") for the rtmpUrl value.​

2) Re-publish in server log is stopped immediately after playing.​

3) youtube streaming fails, but startup RestAPI succeeds.​

Is it possible to handle errors in startup api?
A handling (Fail) is required for specifying an invalid rtmpURL.
As an alternative, I checked push/find_all immediately without delay after calling the push/startup api, but it was all 200 ok, so I couldn't use it.
Of course, if you give it some delay, find_all will return a 404 (stop).

How do I deal with it? Please comment.
Thanks.

Good day.

Is it possible to handle errors in startup api?

If you've specified an RTMP server address which cannot be resolved, /push/startup returns 409 Confilct
But, if you've specified right RTMP server address but a wrong stream key, the connection is establishing successfully and asynchronously. So you have to use /push/find_all with a pause.
Another option is to use REST hook /ConnectionStatusEvent in flashStreamingApp backend application. When Youtube drops the connection due to wrong stream key, this hook will show status DISCONNECTED:
