Error while parsing the 'sandbox' attribute: 'allow-downloads' is an invalid sandbox flag in ms team

Hi,

 

I have developed an application for MS teams where I am using silent sign in using Azure Graph API. It is working fine in MS Teams Web View but it not working in MS Teams Desktop View. When I debugged, I am getting error as "Error while parsing the 'sandbox' attribute: 'allow-downloads' is an invalid sandbox flag.". 

 

Thanks,

      Nikitha-MSFT I am developing a MS teams app where I am getting logged in user information using Graph API. just implementing SSO in MS teams Tab. 

       

      I have created an aspx page where I used adal.js to implement SSO. Below is the code I used. 

      <script type="text/javascript">
      microsoftTeams.initialize();
      window.config = {
      instance: "https://login.microsoftonline.com/",
      tenant: "common",
      clientId: "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
      postLogoutRedirectUri: window.location.origin,
      cacheLocation: "localStorage",
      endpoints: {
      "https://graph.microsoft.com": "https://graph.microsoft.com"
      }
      };

      var authContext = new AuthenticationContext(window.config);
      if (authContext.isCallback(window.location.hash))
      authContext.handleWindowCallback(window.location.hash);
      else {
      var user = authContext.getCachedUser();
      if (!user)
      authContext.login(); // No cached user...force login
      else {
      authContext.acquireToken("https://graph.microsoft.com", function (error, token) {
      if (error || !token) {
      authContext.login();
      }
      else
      microsoftTeams.authentication.notifySuccess(token);
      $.ajax({
      url: 'https://graph.microsoft.com/v1.0/me/',
      headers: { 'authorization': 'Bearer ' + token },
      type: 'GET',
      dataType: 'json'
      }).done(function (res) {
      document.write(res['userPrincipalName']);
      console.log(res['userPrincipalName']);
      });
      });
      }
      }
      </script>

       

      The above is working good in Web View of MS Teams and getting user information, but it is not working in MS Teams Desktop View. When I debugged in Desktop View, I am getting error as "Error while parsing the 'sandbox' attribute: 'allow-downloads' is an invalid sandbox flag in ms" in console.

       

      Thanks,

      Rajesh
