[SIP Beyond VoIP] sylkpush-server google fcm failed with error 400

[Tijmen de Mes]

Hi,

I can't tell from your logs what is wrong. Clearly firebase receives a wrong JSON request. Which version are you using?

What JSON is transmitted towards firebase? You should see this in the debug log.

Best regards,

> I am receiving an error from FCM side, could you please help me out because I don't see time_to_live, priority to the sylk-pushclient and also it gives me an error on "to" header also also that cannot find field. In the opensips.cfg example I see pusher.py script which I cannot find anywhere in repo. So could you please clarify what I am doing wrong?
