MongoDB Error 213: Duplicate Session Detected
Description
Error 213, 'Duplicate Session', indicates an attempt by a client to create or re-establish a session with an identifier that is already active or known to the MongoDB server. This often occurs when client applications improperly manage session lifecycles or when network conditions lead to ambiguous session states.

Known Causes

A network issue causes the client to retry session creation while the original session, though potentially dormant, is still considered active by the server.
Misconfigured Application Logic
