RVR-VM-300

Issue summary

The error code RVR-VM-300 with the description Get column mappings error indicates a problem retrieving or setting up column mappings during the data transfer process in Data Integration when using the Verta Media data connector. This error typically occurs due to changes in the source schema, missing or incorrectly configured mappings, data type mismatches, or column definitions that are not properly mapped.

Action steps

To resolve this issue, follow these steps:

1. Check Column Mapping Configuration: Navigate to the column mapping section within your Data Integration console for the specific Data Flow using the Verta Media connector. Ensure all required columns from the Verta Media data source are correctly mapped to your target schema. Pay particular attention to whether any new columns have been added or if there have been schema changes that need addressing. Ensure no columns have invalid characters or unsupported data types.
2. Evaluate Data Types: Confirm that there are no data type mismatches between the source and target columns. Confirm that the data types used in your mappings conform to supported Data Integration types. If necessary, adjust any column types that might cause conflicts or errors.
3. Review Schema for Updates: Verify that the schema of the data source has not recently changed, as schema changes require updates to the mapping configuration in Data Integration. Reload or refresh your metadata to update the schema mappings.
4. Examine Data Flow Settings: Check your Data Flow settings and ensure configurations such as Auto Mapping use the correct values. Incorrect settings can cause improper mapping.
5. Rerun Auto-Mapping: Use the auto-mapping feature in Data Integration to regenerate the column mappings. This can help automatically align source and target columns and correct issues where columns have changed or were initially mapped incorrectly.
6. Test Connection and Configuration: Make sure the connection to Verta Media is active and correctly configured. You can test this from the Data Integration interface to ensure a stable link between Data Integration and Verta Media.
7. Check for Recent Changes: If this error started recently, review any changes made to the Data Flow, including schema changes or updates in the Verta Media system that the current mappings do not reflect.
