microsoftTeams.authentication.getAuthToken is not working in sharepoint.

We are using below code snippet

  microsoftTeams.authentication.getAuthToken({
                successCallback: (result) => {
                   getMSGRAPHTokenFROMServer(result).then(function (accessTokenResponse) {
                        var graph_response = JSON.parse(accessTokenResponse.graph_response);
                        this._accessToken = graph_response.access_token;
                        dfd.resolve(true);                           
                    }.bind(this), function (error) {
                        dfd.reject(error);
                    })
                },
                failureCallback: function (error) {
                    dfd.reject("Error getting token: " + error);
                },

            });

It works find in Teams by not working in SharePoint.

Hi @ChetanSharma-msft ,

I am not using SPFX.
It's simple node js application.

Unfortunately getAuthToken (and most of the teamsjs functions) are not supported when running your Teams app in SharePoint (for reference: #1407). Also unfortunately, the SharePoint team does not clearly document what does and does not work in this scenario. Their primary documentation page is here:
https://learn.microsoft.com/en-us/microsoftteams/platform/tabs/how-to/tabs-in-sharepoint
...but it doesn't nearly go to the level of detail needed (like support for individual capabilities or functions). As such, I will work with the SharePoint and documentation team to make the level of support clearer.

In the meantime, unfortunately getAuthToken (and most functions besides app.getContext().app.sharePoint) are not supported when Teams apps run in SharePoint.
