carloea2 opened a new issue, #8163:
URL: https://github.com/apache/texera/issues/8163
### What happened?
A malformed workflow WebSocket frame fails during JSON deserialization
before the endpoint enters its existing error handler. The server logs the
parse exception, but the connected editor receives no `WorkflowErrorEvent` and
keeps waiting without an explanation.
Before: malformed frame logs an exception and sends no error event.
After: malformed frame follows the normal workflow error path and sends
`WorkflowErrorEvent` with the parse failure.
Valid heartbeat frames must continue to receive `HeartBeatResponse`.
### How to reproduce?
1. Start the computing unit master from main.
2. Connect to the workflow WebSocket with valid workflow and computing unit
parameters.
3. Send the incomplete JSON frame `{`.
4. Observe the normal startup events, but no workflow error event. The
client eventually times out.
