WS validation error

Code

WS/VALIDATION_ERROR

What it means

The server received a WebSocket message, but the payload failed validation against the expected DTO/schema.

When it happens

• A WebSocket message payload fails DTO/schema validation.

Typical scenarios:

• Client and server DTO versions are out of sync
• Client sends malformed payloads (missing required fields, wrong types)
• A message router maps the wrong DTO to a type

How to handle

• Treat as 400-class client error.
• Include a compact validation reason in meta.reason (avoid huge payload dumps).
