Redis stream adapter & socket.io-sticky

[JojoRebondy]

Hi,

I'm trying to use socket.io-sticky library with a socket.io Redis stream adapter.

My use case is the following, I have several severs (A & B) and I have several worker on each server. I saw the following picture on your README.md and it feels like it's exactly my use case.

I tried implementing both library like such:

on the worker side:

const httpServer = Http.createServer(); const io = new Server(httpServer); io.adapter(createAdapter(redis)); setupWorker(io);

on the primary side: ` const httpServer = http.createServer();

setupMaster(httpServer, {
    loadBalancingMethod: "least-connection"
});
httpServer.listen(3000);`

I'm not using Express but directly the node internal Http library.

When I start the application I get no errors (all the setup part seems to be working fine) but whenever I create a websocket connection I get this error that crashes my application:

`node:internal/assert:14 throw new ERR_INTERNAL_ASSERTION(message); ^

Error [ERR_INTERNAL_ASSERTION]: This is caused by either a bug in Node.js or incorrect usage of Node.js internals. Please open an issue with this stack trace at https://github.com/nodejs/node/issues

I don't really understand what I'm doing wrong so I'm just curious if implementing socket.io-stiky with a redis stream adapter is doable or not.

If anyone have any informations regarding the subject, it would be greatly appreciated.

Thanks in advance.
