S3 Data Provider Search Failing With No Results And No Error Messages

I setup a S3 Data Provider & Dataset with appropriately regex'd directory pathing (tested to validate and it passes everytime)... but even with that, I am unable to search data within the S3 bucket. I have two primary root directories in this S3. Within the Datasets I have two bucket paths defined. One is working fine, but the other successfully searches, but generates no results and gives me no errors... It's very hard to troubleshoot / debug when you get no errors. I'd even take a 'no such directory/path exists', that would at least help me define my troubleshooting pathway. Anyone have any words of wisdom to impart so that I can try to fix this path search?
