Can't send notifications from Parse Server

Question

I am trying to send push notifications from Bitnami Parse Server (3.1.2) hosted on AWS. I have the server key and the sender ID from firebase in server.js. Notifications work from the firebase console but not from parse server (neither from the dashbord nor from REST API). It says it's saved but Pushes Sent appear 0 even though I have two installations.

Any ideas?
