MongoDB Error 151: Operation Cannot Be Batched
Description
This error indicates that a specific database operation is not suitable for execution within a batch or bulk write context. It typically occurs when attempting to include commands or operations that are inherently single-execution, have complex dependencies, or are explicitly marked as unbatchable by MongoDB, preventing safe concurrent processing.
Error Message
Operation Cannot Be Batched
Known Causes
3 known causesIncompatible Operation Type
Attempting to include an operation within a bulk write that MongoDB explicitly does not support for batching, such as certain administrative commands or complex aggregation stages.
Operations with Ordering Dependencies
Using operations that require a specific execution order or have side effects that make parallel processing within a batch unsafe or impossible.
Driver API Misuse
Incorrectly using a driver's bulk write API for an operation that should be executed individually, leading the server to reject the batched command.
