title: 'Invalid Signature' error for Access Token (azure active directory / msal js)
body: <p>I used MSAL JS for authenticating user &amp; thereafter calling acquireTokenPopup(scopes) for Access Token.</p>
  
  <p>I am getting the access token, but cannot use it as it says <strong>Invalid Signature</strong>. 
  (checked in jwt.io too - same error)</p>
  
  <p>Over the forum I found it is due to Graph adding nonce.
  What will be the solution?
  Please help.</p>
  
  <p>Following is the code.</p>
  
  <pre><code>tenantConfig = {
      scopes: ["directory.read.all"]
  };
  </code></pre>
  
  <p>this.clientApplication.acquireTokenSilent(this.tenantConfig.scopes).then(
                  function (accessToken) {</p>
  
  <pre><code>            },
              function (error) {
                  console.log(error);
                  this.clientApplication
                      .acquireTokenPopup(this.tenantConfig.scopes)
                      .then(
                          function (accessToken) {
  
                              console.log("access token   " + accessToken);
                          },
                          function (error) {
                              alert(error);
                          }
                      );
              }
          );
  </code></pre>
