MongoDB Error Types
- Network Errors: These errors occur when there are issues with the network connection between your Node.js application and the MongoDB server. Examples include connection timeouts, network failures, or server unavailability.
- Validation Errors: MongoDB enforces schema validation, and errors can occur when data doesn’t meet the defined schema requirements, such as missing required fields or data type mismatches.
- Duplicate Key Errors: MongoDB throws errors when attempting to insert or update a document with a duplicate key value in a unique index.
- Write Errors: These errors occur during write operations such as inserts, updates, or deletes. Examples include write conflicts, write concern failures, or write operations exceeding the server’s limitations.
- Query Errors: Errors can also arise from incorrect query syntax, invalid aggregation pipeline stages, or unsupported operations.
