RVR-MGB-400
Issue summary
- The error "MongoDB different ids types error" with the code RVR-MGB-400 occurs when there is a mismatch in ID types used in a MongoDB collection. This often happens when the data in MongoDB has inconsistencies regarding the types used for IDs across different documents. This can happen due to manual data entries or inconsistent data schema enforcement in collections.
Action steps
To resolve the error, follow these steps:
- Identify the Cause:
- Check your MongoDB collection for documents with different IDs (such as ObjectId, string, or integer) and ensure that they are consistent.
- Use MongoDB shell or a script to iterate over the collection and report documents with mismatched ID types.
- Standardize ID Types:
- Convert IDs to a consistent type across your entire collection. It is common to use
ObjectIdfor MongoDB, but if string IDs we recommend, ensure all IDs are strings. - You may use an aggregation framework or a custom script to update IDs to a consistent type.
- Convert IDs to a consistent type across your entire collection. It is common to use
- Update Schema Definitions:
- If applicable, update your application code or schema definitions to enforce the desired ID type on all new documents inserting.
- Validate Changes:
- After standardization, validate data consistency by running queries to check for any remaining discrepancies.
