How to pass websocket client to master process in nodejs?

Question

JavaScript

Good afternoon!
I am working with sockjs. When a stream object (client) arrives, I send it through the worker to the master process.
process.send({ client: connection })
connection is a stream object (client).
And when I call the send method, I get an error:

internal/child_process.js:609
var string = JSON.stringify(message) + '\n';
                      ^
TypeError: Converting circular structure to JSON

.
With ordinary objects, everything is fine. Tell me how to fix

Answer 1

Pass connection as the second parameter to process.send
