WebSocket 1009 Message Too Big vs 1014 Bad Gateway
Both WebSocket 1009 (Message Too Big) and 1014 (Bad Gateway) belong to the WebSocket Close Codes category. 1009 indicates that an endpoint is terminating the connection because it received a message that is too large for it to process. Meanwhile, 1014 means that the server acting as a gateway or proxy received an invalid response from an upstream server it accessed while attempting to fulfill the request.
설명
An endpoint is terminating the connection because it received a message that is too large for it to process.
이 코드를 보게 되는 경우
The message payload exceeded the server's configured maximum frame or message size limit. Common when uploading large files or sending huge JSON payloads over WebSocket.
해결 방법
Reduce the message size by chunking large payloads into smaller frames. Alternatively, increase the server's max message size configuration if the large payload is expected.
설명
The server acting as a gateway or proxy received an invalid response from an upstream server it accessed while attempting to fulfill the request.
이 코드를 보게 되는 경우
A reverse proxy or API gateway tried to establish a WebSocket connection to a backend server but received an invalid or no response. The upstream server may be down or misconfigured.
해결 방법
Check the health of the upstream/backend WebSocket server. Verify the proxy configuration routes WebSocket upgrade requests correctly and that the backend is listening on the expected port.
