Description

Hi team,

Application: Blazor Server Render Mode: Interactive Sign-in through Azure B2C

I am trying to fetch the access token using token acquisition but it never completes.

Reproduction steps

  1. try to fetch the token using Itokenacquisition, providing the scope public async Task GetTokenAsync() { var accessToken = await _tokenAcquisition.GetAccessTokenForUserAsync(new[] { _myAppScope }); return accessToken; }

Error message

Microsoft.Identity.Web.TokenAcquisition: Information: [MsIdWeb] An error occured during token acquisition: No account or login hint was passed to the AcquireTokenSilent call.

Expected behavior

Expected to get access token

Anyone managed to get this working with the Profile editing user flow? I can retrieve the access token when the user is logged in fine. But as soon as I change details, GetAccessTokenForUserAsync crashes with "No account or login hint was passed to the AcquireTokenSilent call.".
