javascript有效修补程序文档错误

尝试在VSTS I中创建工作项成功。但是，当我还想为字段System.AreaPath赋值时，我失败了

我的代码（工作和不工作System.AreaPath）：

代码包括{\“op\”：“add\”，“path\”：“/fields/System.AreaPath\”，“value\”：\“+area+”}

给出错误：

{“$id”：“1”，“innerException”：null，“message”：“您必须传递一个有效的 文档正文中的修补程序文档 请求“，”类型名称“：”Microsoft.VisualStudio.Services.Common.VSSPPropertyValidationException， Microsoft.VisualStudio.Services.Common，版本=14.0.0.0， 文化=中立， PublicKeyToken=hidden”，“typeKey”：“VssPropertyValidationException”，“errorCode”：0，“eventId”：3000}

我缺少什么？

替换

var area=“TestProject1\\area 51”至
var area=“TestProject1\\\\area 51”

顺便说一下，您在代码中指定了多个区域键

  var number = "1234";
var title = "Test Title";
var caller = "Test Caller";


var assignment_group = "Test Group";
var tags = "Bug";
var area = "TestProject1\\Area 51";
var assigned_to = "Test To";



        var url = "https://[instance].visualstudio.com/DefaultCollection/TestProject1/_apis/wit/workitems/$Bug?api-version=2.2";
        var request = new sn_ws.RESTMessageV2();
        request.setEndpoint(url);
        request.setHttpMethod('PATCH');

        var password = 'somePassword';

        request.setBasicAuth(password);
        request.setRequestHeader("Accept","application/json");
        request.setRequestHeader('Content-Type','application/json-patch+json');
        request.setRequestBody("[{\"op\":\"add\",\"path\":\"/fields/System.Tags\",\"value\":\""+tags+"\"},{\"op\":\"add\",\"path\":\"/fields/System.Title\",\"value\":\"[" + number + "] " + title + "\"},{\"op\":\"add\",\"path\":\"/fields/Microsoft.VSTS.TCM.SystemInfo\",\"value\":\"Assignment Group: "+assignment_group+"\nCaller: "+caller+"\nAssigned to: "+assigned_to+"\"}]");
        var response = request.execute();

// {\"op\":\"add\",\"path\":\"/fields/System.AreaPath\",\"value\":\""+area+"\"}
