'WebSocket Single Read Sampler': Pong frame with no application data

[Chhavi Jain]

Hi Peter,

My application is sending unsolicited Pong frame every few seconds and the Read sampler is failing because of this. I have seen your previous posts and aware of a ping filter post however, that is specifically for ping. I tried putting a WebSocket Text Frame Filter on top of the Read Sampler such that it discards any frame that does not contain text however, it is not able to filter out the pong frame.

Is there a way to get over this limitation of read sampler or ignore the pong frames so that the script can proceed further. Please help me at the earliest as I am blocked because of this issue.

Below is the error message being thrown:

2020-11-30 12:48:39,470 ERROR e.l.j.w.SingleReadWebSocketSampler: Unexpected frame type received in sampler 'WebSocket Single Read Sampler': Pong frame with no application data

I noticed in one of the thread that along with the ping filter, you have developed a pong filter as well. I have found it, thanks again. I am closing the issue myself.

Found the pong filter that would be useful in this case.
