WebSocket 1002 Protocol Error vs 1007 Invalid Payload Data
Both WebSocket 1002 (Protocol Error) and 1007 (Invalid Payload Data) belong to the WebSocket Close Codes category. 1002 indicates that an endpoint is terminating the connection because it received data that violates the WebSocket protocol specification. Meanwhile, 1007 means 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.
Açıklama
An endpoint is terminating the connection because it received data that violates the WebSocket protocol specification.
Gördüğünüzde
The WebSocket frame format is invalid — a malformed header, incorrect masking, or a reserved opcode was used. This usually indicates a broken client or proxy.
Nasıl Düzeltilir
Check that both client and server strictly follow RFC 6455 framing rules. Inspect intermediary proxies that may be corrupting WebSocket frames.

Gördüğünüzde
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.
Nasıl Düzeltilir
Ensure text frames contain only valid UTF-8 encoded data. If you need to send raw bytes, use binary frames instead of text frames.
