Use proxy via REST helper

I would like to add a proxy parameter on REST helper, like on webdriver Helper

I don’t know how I have to do

I have error

502 bad gateway

"helpers": {
    "REST": {
      "endpoint",
      "defaultHeaders": {
        "X-APIKey": "test",
        "Authorization": 
        "Accept": "application/json"
      }
    }
  }

        "WebDriver": {
            "url": "http://{{url}}:86/oskar-ng/",
            "browser": "chrome",
            "restart": false,
            "windowSize": "300x800",
            "host": "localhost",
            "port": 4444,
            "desiredCapabilities": {
                "browserName": "chrome",
                "chromeOptions": {
                  "args": [ "--user-agent=Mozilla/5.0 (Linux; Android 7.0; SM-G892A Build/NRD90M; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/60.0.3112.107 Mobile Safari/537.36"]
                },
                **"proxy": {
                  "proxyType": 
                  "proxyAutoconfigUrl": 
                }**
            }
        }
    }

I did this for webdriver but I can’t do it for REST helper

My question: Is there a way to do this ?

I was able to confirm that

By analogy try to pass proxy object to onRequest

“works” – that is, as suggested, the proxy value is passed correctly to axios – but I simply could not get axios to communicate with our proxy the way our proxy expects. This may have been an HTTPS-over-HTTP obstacle (and it would not surprise me that the limitation is in the proxy rather than in axios, but either way).

However, I was able to disable axios’ own proxy configuration and override its HTTP(S) agent with https-proxy-agent@5.0.0 and get that working:

const HttpsProxyAgent = require("https-proxy-agent");

...

  REST: {
    endpoint: "https://reqres.in", // NB: no trailing slash
    onRequest: (request) => {
        if (process.env.https_proxy) {
            // Forcefully disable axios' own proxy config, because it just
            // doesn't work right in our situation.
            request.proxy = false;
            request.httpsAgent = new HttpsProxyAgent(process.env.https_proxy);
        }
        if (process.env.http_proxy) {
            request.proxy = false;
            request.httpAgent = new HttpsProxyAgent(process.env.http_proxy);
        }
    }

I got this solution from an axios ticket.

Maybe this will help, in my case I needed to disable proxy at all:

        REST: {
            endpoint: getEnv('grafUrl'),
            onRequest: (request) => {
                request.proxy = false;
            }
        }

By analogy try to pass proxy object to onRequest

proxy: {
    host: '127.0.0.1',
    port: 9000,
    auth: {
      username: 'mikeymike',
      password: 'rapunz3l'
    }
  }
