WebSocket
1011 Internal Error
The server is terminating the connection because it encountered an unexpected condition that prevented it from fulfilling the request.
When You See This Code
The server hit an unhandled exception or crashed while processing a WebSocket message. This is the WebSocket equivalent of HTTP 500 Internal Server Error.
How to Fix
Check the server-side application logs for stack traces and exceptions. Fix the underlying bug that caused the crash and add proper error handling around message processing.
