This is my and my organization’s first Elixir / Phoenix project so far. I have been able to set up a working prototype and got the green light to turn it into a full product. The only thing so far I haven’t been able to solve myself is the fact that the (iOS, Android and Web) clients send heartbeat …

what client code/libraries are you using? from that error it seems like your client is trying to connect to a “heartbeat” channel, which isn’t quite normal.. (afaik - the heartbeat goes in a “phoenix” channel - but your client lib should handle it all..)

For Swift I’m using SwiftPhoenixClient. Seeing this in my output: socket received: {"topic":"heartbeat","ref":"3B151654-07A0-4BED-9C09-27F5881B6118","payload":{"status":"error","response":{"reason":"unmatched topic"}},"join_ref":null,"event":"phx_reply"} Phoenix Response: ref:"3B151654-07A0-4BED-9C…

There’s also GitHub - sjrmanning/Birdsong: 🐦🎼 Swift WebSockets client for Phoenix Channels. · GitHub for swift which doesn’t have this particular error …

is it also the js client? or only the swift one? (that breaks)

I just compared to be sure. But Birdsong isn’t super actively updated while SwiftPhoenixClient is. I’m trying to update SwiftPhoenixClient now, it was a while since I updated it.

There isn’t much to a phoenix channel client. phoenix.js isn’t often updated either … As for the SwiftPhoenixClient, it was abandoned before someone else picked it up and started rewriting it.

OK guys we can wrap it. A newer version works great. So it was sending the wrong message all of the time. @idi527 thanks for the hint, luckily the library is maintained.

I notice. There’s a ton of API changed. Have to rewrite my code and try again.
