Hi @uday31in. Thank you for reaching out and we regret that you're experiencing difficulties. Unfortunately, this is not an issue that the Azure SDK team can assist with.

The Azure.Identity credentials have no insight nor influence over which credentials are supported by the local Managed Identity endpoint for the Functions host. Likewise, the Azure SDK team has no insight into the Azure portal nor how they are using our libraries. As a Microsoft internal, I'd suggest opening an IcM for the Functions team, as you'll need their insight to understand the root cause and path forward.
