WebSocket 1000 Normal Closure vs 1007 Invalid Payload Data
Both WebSocket 1000 (Normal Closure) and 1007 (Invalid Payload Data) belong to the WebSocket Close Codes category. 1000 indicates that the connection has been closed cleanly, meaning the purpose for which it was established has been fulfilled. Both endpoints agree the session is complete. 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.
Descripción
The connection has been closed cleanly, meaning the purpose for which it was established has been fulfilled. Both endpoints agree the session is complete.
Cuándo lo verás
The WebSocket connection closed gracefully after both sides finished exchanging data. This is the expected close code for a successful session.
Cómo solucionarlo
No fix needed — this indicates everything worked as intended. If you did not expect the connection to close, check your application logic for premature close() calls.
Descripción
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.
Cuándo lo verás
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.
Cómo solucionarlo
Ensure text frames contain only valid UTF-8 encoded data. If you need to send raw bytes, use binary frames instead of text frames.
