WebSocket 1007 Invalid Payload Data vs 1012 Service Restart
Both WebSocket 1007 (Invalid Payload Data) and 1012 (Service Restart) 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, 1012 means that the server is terminating the connection because it is restarting. The client should reconnect after a brief delay.
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.
Descripción
The server is terminating the connection because it is restarting. The client should reconnect after a brief delay.
Cuándo lo verás
The server is performing a planned restart — for example, during a deployment or configuration reload. The connection will be available again shortly.
Cómo solucionarlo
Implement automatic reconnection with a short delay (1-5 seconds). This code signals that reconnecting is expected and should succeed once the server is back up.
