PDF Text is Successfully indexed but doesn't return results

Hello -

I am developing a solution to index and search PDF text of media entities associated to a content type. I am hosting on Pantheon using Drupal 9, SOLR 3.6.2, the TIKA extractor. I have tried with both version 8.x-1.0-beta18 and also tried upgrading to 9.0.x-dev when that wasn't working with no luck. I have the PDF text successfully indexing in SOLR but when I create the view with the Fulltext search filter based on the steps in the ReadMe file it always returns 0 results but the content is indexed, it's just not returning when searching in the view.

Versions of Modules currently in Use

Search API 8.x-1.21
Search API Pantheon 3.0.1
Search API Solr 4.2.2
Search API Attachments 9.0.x-dev (but also had the same results using 8.x-1.0-beta18)

I know the ReadMe examples were tested using Drupal 8.8 but it seems like it should work the same otherwise. Any guidance would be much appreciated, thank you!
