After input of credential to Microsoft login (pop up modal) i am facing this below Error !! about msgraph-sample-angularspa HOT 2 CLOSED

This error is common if you register your application as a single-tenant app (choose Accounts in this organizational directory only when creating the registration). The app is written as a multi-tenant app and uses the /common authentication endpoint. (Note that the app registration instructions specify to register as multi-tenant).

For single tenant, you need to configure msal-angular to use your tenant-specific auth endpoint. You would want to add an authority value in this block:

It would look something like:

authority: 'https://login.microsoftonline.com/YOUR_TENANT_ID'
