WebSocket 1007 Invalid Payload Data vs 1008 Policy Violation
Both WebSocket 1007 (Invalid Payload Data) and 1008 (Policy Violation) belong to the WebSocket Close Codes category. 1007 indicates that an endpoint received a message with payload data that is inconsistent with the message type. For example, a text message contained non-UTF-8 data. Meanwhile, 1008 means that an endpoint is terminating the connection because it received a message that violates its policy. This is a generic code when none of the other codes (1003, 1009) are suitable.
คำอธิบาย
An endpoint received a message with payload data that is inconsistent with the message type. For example, a text message contained non-UTF-8 data.
เมื่อคุณพบเห็น
A text frame was received but its payload is not valid UTF-8. This commonly happens when binary data is accidentally sent as a text frame.
วิธีแก้ไข
Ensure text frames contain only valid UTF-8 encoded data. If you need to send raw bytes, use binary frames instead of text frames.

เมื่อคุณพบเห็น
The server rejected a message because it violated an application-level policy — for example, sending messages too rapidly, exceeding rate limits, or failing authentication after the handshake.
วิธีแก้ไข
Review the server's documented policies and constraints. Check for rate limiting, authentication token expiry, or forbidden message content that triggered the rejection.
