How to set up and validate locally

Note

You might not have the data needed for manual testing without Geo enabled in your GDK. In this case, I would recommend that we mock the API response in getModelList with the following (paste it in your editor):

[{"record_identifier":6,"model_class":"SnippetRepository","created_at":null,"file_size":null,"checksum_information":{"checksum":"abc0","last_checksum":null,"checksum_state":2,"checksum_retry_count":null,"checksum_retry_at":null,"checksum_failure":null}}]

Alternatively, we could request for another review from the Geo team members to validate its behavior.

1. Add EE license to your instance.
2. enable the geo_primary_verification_view feature flag through /rails/features
3. Go to /admin/data_management
