Subject: [PATCH] Enhance MemberTransferService with detailed debug logging for
 login credentials

Added comprehensive debug logging to the MemberTransferService to track login credentials and endpoint details during member transfers. Implemented checks for the presence of login credentials, including mapping username to email when necessary, and improved error handling for missing credentials. This enhancement aims to facilitate troubleshooting and improve the overall robustness of the login process.
