Hasura support helped me pinpoint it to the metadata stored in the Graphql console. Hope this helps someone else save a little time.
"If you make DDL changes to your database from outside Hasura, you must manually reload the Hasura metadata so that Hasura knows that something has changed and it adapts to those changes accordingly.You can reload the metadata by clicking on the settings icon on the top right in console."
