WebSocket 1007 Invalid Payload Data vs 1013 Try Again Later
Both WebSocket 1007 (Invalid Payload Data) and 1013 (Try Again Later) 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, 1013 means that the server is terminating the connection due to a temporary condition, such as being overloaded. The client should reconnect after a back-off period.
설명
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.
이 코드를 보게 되는 경우
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.
해결 방법
Ensure text frames contain only valid UTF-8 encoded data. If you need to send raw bytes, use binary frames instead of text frames.
설명
The server is terminating the connection due to a temporary condition, such as being overloaded. The client should reconnect after a back-off period.
이 코드를 보게 되는 경우
The server is temporarily overloaded or throttling connections. Unlike 1012, this does not indicate a restart — the server is running but cannot serve more clients right now.
해결 방법
Reconnect using exponential backoff (start at 1 second, double each attempt). If persistent, investigate server capacity, scale horizontally, or reduce the number of concurrent connections.
