what "modifications" were made to the json

I have been unable to replicate the sample because I have been unable to get glue to crawl the json file that I have downloaded from EveryPolitician.com. Maybe you could share your .json file with the modifications that were made or tell us what modifications need to be made.

"It contains data in JSON format about United States legislators and the seats they have held in the the House of Representatives and the Senate, and has been modified somewhat for purposes of this tutorial."

My crawler never detects these tables:
persons_json
memberships_json
organizations_json
events_json
areas_json
countries_r_json

Start with the tutorial referenced in the issue and reproduce the AWS Glue crawler against the downloaded EveryPolitician JSON. Compare the result with the six expected tables—persons_json, memberships_json, organizations_json, events_json, areas_json, and countries_r_json. Done means the repository documents the modifications or provides the modified JSON so the crawler detects those tables.
