When new data containing undefined fields is exported, Mona automatically generates a suggested configuration for these new fields. If you wish to adjust the configuration before exporting data with new fields, you can use this endpoint to retrieve the suggested configuration without exporting the data itself. This allows you to upload the correct configuration in advance, helping you avoid the need for backfills.
Following this approach is considered best practice before exporting new fields to Mona.
