MongoDB Error 90: Callback Canceled Operation
Description
Error 90, 'Callback Canceled', indicates that an asynchronous MongoDB operation was initiated but its corresponding callback function was never invoked. This usually happens when an operation is aborted or times out before completion, often due to client-side issues or network instability.
Error Message
Callback Canceled
Known Causes
4 known causesClient Operation Canceled
The application explicitly canceled an asynchronous MongoDB operation or a client-side timeout expired before the operation could complete.
Network Instability

Application Logic Error
Issues within the application's asynchronous logic or improper handling of MongoDB driver operations led to the callback being prematurely canceled.
Server Unavailability
The MongoDB server became unavailable (e.g., shut down or restarted) during an active operation, causing the client's pending callback to be canceled.
