WebSocket 1003 Unsupported Data vs 1009 Message Too Big
Both WebSocket 1003 (Unsupported Data) and 1009 (Message Too Big) belong to the WebSocket Close Codes category. 1003 indicates that an endpoint received a type of data it cannot accept. For example, a text-only endpoint received a binary message, or vice versa. Meanwhile, 1009 means that an endpoint is terminating the connection because it received a message that is too large for it to process.
विवरण
An endpoint received a type of data it cannot accept. For example, a text-only endpoint received a binary message, or vice versa.
जब आप इसे देखें
The client sent a binary frame to a server that only handles text, or a text frame to a binary-only endpoint. The receiver does not know how to process this data type.
कैसे ठीक करें
Verify the message type (text vs binary) matches what the server expects. Update your client to send the correct opcode for the data format.
विवरण
An endpoint is terminating the connection because it received a message that is too large for it to process.
जब आप इसे देखें
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.
कैसे ठीक करें
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.
