Question Steam Market HTTP Error 502

[chaot1c]

Getting a error when trying to execute this code:

community.httpRequestPost('https://steamcommunity.com/market/sellitem/', {
        form: {
          sessionid: community.getSessionID(),
          appid: item.appid,
          contextid: item.contextid,
          assetid: item.assetid,
          amount: 1,
          price: 10000 // 10000 == $100
        }, 
        headers: headers,
        json: true
      }, (err, response, json) => {
        if(err) {
          console.log(`Sell item HTTPREQUESTPOST error: ${err.toString()}`);
          return;
        }

        console.log(json);

      }, "steamcommunity");

My headers are:

 

'Host': 'steamcommunity.com',

'Origin': 'https://steamcommunity.com'

'Referer': 'https://steamcommunity.com/market/'

'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.99 Safari/537.36',

'X-Requested-With': 'XMLHttpRequest',

 

Cookies: (first 4 getting from node-steam-tradeoffer-manager)

webTradeEligibility (from your's reddit post)

I've tried to do request from REST Client with client's account cookies, headers, and it works (from client, not from node).

502 = Bad Gateway

 

Have you tried again after some time?

502 = Bad Gateway

 

Have you tried again after some time?

httpRequestPost returns only 502, but there is a message: 

{
  "success": false,
  "message": "There was a problem listing your item. Refresh the page and try again."
}
