Teams Personal App Development

New Contributor

I was developed a teams personal app with "Teams ToolKit". The app is working well in the web version of Teams. But In desktop and Mobile client not working properly. My personal app contains a module about fetching current and all users details using GraphClientfactory.  My app failed to load when calling the graph API module. In the web version, it's working correctly. I don't know what is the issue arise when calling graph call? 


Here anyone faces the same issue?
please help me. I am stuck for about 2 weeks.

Thanks In advance.

@Kameshm05 - Could you please the Graph API docs which you are referring, so that we can test it from our end.
Also could you please share the console log/error details from Teams Desktop client.

@ChetanSharma-msft hi Chetan Sharma, Thanks for the reply. I am referred the below link for graph call


In the web version, there is no issue , data loaded correctly. But In the desktop version issue arose.
I am using the alert popup to lock the error message. But that message is shown as undefined. In the log not showing enough details to trace the issue.

I am using the below code in my ts file

        .then((client: MSGraphClient): void => {
          this.graphClient = client;
        }, err => reject(err));

I am using the below code in my TSX file

      const currentUser = await (user,error) => {
        if(error) {


Thanks, Chetan Sharma
