WebSocket 1007 Invalid Payload Data vs 1014 Bad Gateway
Both WebSocket 1007 (Invalid Payload Data) and 1014 (Bad Gateway) 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, 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.
説明
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.
このコードが表示される場合
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.
解決方法
Ensure text frames contain only valid UTF-8 encoded data. If you need to send raw bytes, use binary frames instead of text frames.
説明
The server acting as a gateway or proxy received an invalid response from an upstream server it accessed while attempting to fulfill the request.
このコードが表示される場合
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.
解決方法
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.
