Valid FuzzyDB Extracted data is being marked as invalid in the Validation Page. They were using Read-only indexes and hidden fields that were not able to be validated.
The correct Validation of extracted data depends on a few things:
1. The Validation Pattern Defined in the batch Class
2. OCRConfidenceThreshold of an index field (Default = 90)
If Any of these Constraints are not met then your index fields will be marked as invalid and your batch will either stop in validation or cannot be validated.
To get around this you will need to do one of two things:
1. Remove your validation patterns for the index fields being mapped with Fuzzy DB.
2. Set the OCRConfidenceThreshold to 0
By doing this your FuzzyDB extracted values will not cause an issue even if you are using Read-Only or Hidden Fields.
