How to upload test result from TestComplete to QAComplete using POST request.

How to upload test result from TestComplete to QAComplete using POST request. I'm planning to upload the .mht file from TestComplete result to QAComplete. This is my code to upload the file but it didnt work.

var url4 = 'https://qacomplete.smartbear.com/rest-api/service/api/v2/projects/(projID)/testruns/' + runID +'/items/' + itemId +'/report';

var value = Bytes();

var files = '{"file":'+ value +'}';

var aqHttpRequest4 = aqHttp.CreatePostRequest(url4,username,password);

aqHttpRequest4.SetHeader("Content-Type", "application/json");

var aqHttpResponse4 = aqHttpRequest4.Send(files);

if(aqHttpResponse4.StatusCode == "200"){

Log.Message(aqHttpResponse4.Text);

} else {

Log.Error("Error");

}

I'm getting this error when I run the code.

url4 = https://qacomplete.smartbear.com/rest-api/service/api/v2/projects/(projID)/testruns/1176706/items/8840000/report

Any idea?
