Bulk Data Migrations Using `Operations` between two CosmosDBs fails when using RBAC auth

[CBennettAtBrock]

When trying to migrate data between two CosmosDB accounts using the Operations section fails when you use RBAC auth with:
System.InvalidOperationException: This instance has already started one or more requests. Properties can only be modified before sending the first request.

The exact same configuration using a ConnectionString works but AccountEndpoint with UseRbacAuth gives the previous error.

Example failing config:

same here, tried both to azure storage account and another cosmos instance and got the same errors

@brazarb / @CBennettAtBrock, the UseDefaultCredentials option modifies the HttpClient connection to use your default credentials Connection Settings. It's meant for scenarios where you are behind a proxy. Do you see the same behavior if you remove that setting and supply UseRbacAuth? You can optionally supply EnableInteractiveCredentials if you'd like to be prompted to login.
