Looks like it worked fine and it’s loading normally for anyone else wondering

@here for those who are having issues, I think @david and I may have found the root cause but it’s complicated to reproduce locally. Could any of you run the following SQL queries and report the results here? Query #1 SELECT table_schema, column_name, column_default FROM information_schema.column…
