I have a custom Microsoft Teams application built with Angular. Until recently, all various authentication pipelines were working using SSO “onBehalf”. The main authentication areas are:

1. Custom (dotnet core) WebAPI

2. Microsoft Graph API

3. Microsoft Grapy Toolkit (MGT) components, like mgt-login, etc. 

After updating to

@azure/msal-angular (3.0.17)

@azure/msal-browser (3.14.0)

@microsoft/mgt (4.2.1)

@microsoft/mgt-element (4.2.1)

@microsoft/mgt-teamsfx-provider (4.2.1)

The Microsoft Graph Toolkit components are no longer working. (custom api and graph api still are working fine).

The error message I get is:

Cannot get access token due to error: ErrorWithCode.UiRequiredError: Failed to get access token cache silently, please login first: you need login first before get access token.

I’ve trying to fix the error for quite some time now. Anybody have an idea what is going on? How to fix this?

Thank you,
