While testing the Websocket URL using JSON Request, we are receiving the error "Received: Close frame with status code 1011 and close reason 'null'"

[Former user]

We tried to test WS using Jmeter. It displays 1011 error code. We are not closing the Request by any means. But displays the error mentioning "frame getting closed" Kindly help. Thanks in advance

Your are receiving a close frame, so the server is closing the websocket connection.

And from https://tools.ietf.org/html/rfc6455:

"1011 indicates that a server is terminating the connection because it encountered an unexpected condition that prevented it from fulfilling the request."

Probably the request you sent to the server did not match the server's expectations.
