Error processing WebSocket message

Hi, I am trying to setup claude-flow Alpha.79 on Arch Linux but it is not working. I get an error during the websocket connection if executing "status" in the webgui. I tried it also locally on the physical machine (localhost) - same error.

$ claude-flow start --ui --swarm --debug --host 0.0.0.0 --public-host 10.x.y.z --claude

Received WebSocket message: ping undefined

I also get this websocket message in the developer tools of the browser:

{"jsonrpc":"2.0","id":null,"error":{"code":-32600,"message":"Invalid JSON message"}}

I'm not sure if it is a bug or a wrong configuration. I would be happy of any hint how to solve it.
