WebSocket I/O error: expected payload of length 58, but can only read 15 bytes

[Former user]

Hi Team

We have faced the issue while reading response data:

WebSocket I/O error: expected payload of length 58, but can only read 15 bytes.

In JMeter, the error appeared when the response size for the transaction was about 5 MB. The error appears each time for the transaction. In the browser, we see that the response message is 34.9 MB.

Could you help with the issue, please?

Hi,

The error indicates that the input stream (i.e. the tcp connection) is closed while reading the websocket frame. This is of course a strange, unexpected situation…. To investigate, i need to be able to reproduce the situation or you would have to create a WireShark capture and send it to me (you can mail it to me to keep it private).

Regards
Peter
