ClientAuthError: User login is required. For silent calls, request must contain either sid or login_hint

Question

I'm using MSAL.js to acquire a silent token and it works ok when i login See my snippet code below

  var userid = _spPageContextInfo.userId;  
    //console.log(email);  
var upn = getUserEmailByLoginName(userid);  
  
var config = {    
    auth: {    
        clientId: "",    
        authority: "https://login.microsoftonline.com/techie.onmicrosoft.com"    
        redirectUri: "someUrl",  
    },    
    cache: {    
        cacheLocation: "localStorage"            
    }    
};    
var requestPermissionScope = {    
     scopes: ["user.read"],  
     loginHint: upn,--setting the email address here e.g ******@xyz.com (is this the loginHint?  
   //extraQueryParameters: {domain_hint: 'organizations'}    
};    

The issue i'm facing though is when another user logs in the get this error below

ClientAuthError: User login is required. For silent calls, request must contain either sid or login_hint

In regards to the loginHint. What value do we need? Is it an email address?

In this article

it says prefered_username. But what is it?

Thanks in Advance

Did you find an answer for this? i am trying to get token from sharepoint online. By using new msal 2.0 the following error is prmopted.
UserAgentApplication is not a constructor.
changing to old msal gives below.
