ERR_INCOMPLETE_CHUNKED_ENCODING when long polling with GET

[amunhoz]

I'm getting this error in chrome with my fallback "socket", using xhr polling.
This "fake socket" create a GET request and keep it alive to send information like a stream.
After around 10 seconds chrome give this error and drops the connection.

I'm putting the JS request library here to test
xhrrequest.zip

How to use:

let req = new xhrRequest(Object.assign({timeout: 60000 }))        
req.ondata = function (data){
            console.log(data)
 }
req.get("http://127.0.0.1:8080/", function(err, data) { 
            if (err)  console.log(err)
 })

---

The response from backend is something like this:

var headers= {
        "connection": "Keep-Alive", 
        "Keep-Alive": "timeout=0", 
}
res.writeStatus(status + " OK")
for (var i in headers) {
      res.writeHeader(i, headers[i])
}
var timer = setInterval(()=>{
    res.write("block info");
},1000}
var timer = setTimeout(()=>{
    clearInterval(timer)
    res.end();
},30000}
