PCF is not working when form context is used

[PCF_USer]

Hi All,

I have build PCF using some of the deprciated Client APis lke

Xrm.Utility.getGlobalContext().getQueryStringParameters().pageType

and Xrm.Page

to get the related details. My problem is when I need to use it to build PCF as there is no way or atleast I can't  find a way to use formContext .

Here is the example of it, I tried to define a fuction and use form context but its giving error in PCF as its not accepting the formContext. Can you please tell me the way because I am afraid if its depricated completly, we need to rework again and if its depricated then what is the timeline for complete block of it???

account1 = Xrm.Page.getAttribute("account").getValue();

var userSettings = Xrm.Utility.getGlobalContext().userSettings;

var currentuserid = userSettings.userId;

if (Xrm.Utility.getGlobalContext().getQueryStringParameters().pageType=="quickcreate"){      

var userId=currentuserid.replace("{", "").replace("}", "");

var req = new XMLHttpRequest();

req.open("GET", Xrm.Utility.getGlobalContext().getClientUrl() + "/api/data/v9.2/systemusers(" + userId + ")?$select=productmarket", false);

req.setRequestHeader("OData-MaxVersion", "4.0");

req.setRequestHeader("OData-Version", "4.0");

req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
