Session cookie for WebSocket connection

I'm hosting a custom web client consuming the REST API, the web client and the API endpoint are in different domains, how can I create sessions that allow me to connect to WebSocket?

I'm doing a POST to /session sending email and password and API access using basic authorization, it works great.
But how can I set these cookies so that I can connect to WebSocket and cross domain?

You probably have to configure CORS. Or just proxy API requests, so it's on the same domain.

By the way, why are you doing POST to /session if you use basic authorization after that?

Where do I configure CORS in traccar to accept socket connection from another domain?

Configuration file. But I would recommend proxy option.

Quando você fala em proxy, se refere ao pacote http-proxy-middleware?
Algo com isso:

const { createProxyMiddleware } = require('http-proxy-middleware');

module.exports = (app) => {
  app.use(createProxyMiddleware('/api/socket', { target: `ws://api.domain.com`, ws: true }));
  app.use(createProxyMiddleware('/api', { target: `http://api.domain.com}` }));
};

I have the same problem. Did you found a solution?
