Opentok livestreaming broadcast request error

Question

When I make a request to start live streaming broadcast to opentok api, I have this error :

{
  "message" : "session cannot be broadcasted when mantis not available. with code 400"
}

In below my request term with postman :

url request

https://api.opentok.com/v2/project/api_key/broadcast

header parameters

X-OPENTOK-AUTH : eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...

Accept : application/json

Content-Type : application/json

EDIT : This query is run in the following context: a session with two stream published. The API key is present as well as the session id.

TokBox Developer Evangelist here.

Based on the error message, it looks like you're trying to start a broadcast with a session that's set to relayed mode. You must set the mediaMode to routed when creating a session so you can leverage OpenTok's media servers and use the broadcast feature.

That's right, thanks ! I had completely forgotten media mode setting... but what is mantis? – Fanga Jun 21 '18 at 20:48
That's internal stuff, no need to worry about that. – Francisco Javier Cano Sandoval Jun 22 '18 at 06:51
Thank you for responding to this SO post! But.. this is a really bad error message, especially when 409 according to API doc means that the broadcast has already been started :) – Kurt J Aug 21 '18 at 23:05
Yes, agreed! I've filed this issue internally :) – Manik Aug 24 '18 at 03:28

You have to put your API Key in the request.

Assuming you're doing it, you cannot do that request like that. First of all, you must create a session, and then, start a broadcast on that session, providing some info inside the POST body:

I hope this helps.

Yes I make all that, I removed my api key for not being seen. And I did the query with 2 publisher. – Fanga Jun 21 '18 at 16:48
can you show here the request you're using to start the broadcast? headers and body as well – Francisco Javier Cano Sandoval Jun 21 '18 at 17:00

Are you using routed or relayed mediaMode for the session? You cannot broadcast a relayed session. – Francisco Javier Cano Sandoval Jun 21 '18 at 17:02
