Issue description and reproduction steps

We hosted a 1st party aad app and it is already onboarded into GCC&GCCH. Recently we planed to onboard to Mooncake. Whe n we started integration test calling graph api, we got below error:
AADSTS90002: Tenant 'b94d39f7-7074-4894-98a5-9162bdefa33a' not found. Check to make sure you have the correct tenant ID and are signing into the correct cloud. Check with your subscription administrator, this may happen if there are no active subscriptions for the tenant.

Pls help investigate the error. Thanks in advance.

Sorry @linhu2020, the SDK cannot investigate bad config. You are expected to configure the correct tenant.
