When subscribing to realtime events of database, the client's websocket receives the messages in the websocket feed, but doesn't call the specific message handler (lambda) in the subscribe. I'm using the self hosted 1.8.1. I'm using the javascript sdk
TL;DR
Realtime messages not processing due to using newer SDK 1.8.1, switch to version 1.9.0, cloud, or old SDK for solution.
