Migration fails because the enum needs at least one row, but my data has rows?

I’m trying to migrate data from Heroku to Docker, following the guide from here https://docs.hasura.io/1.0/graphql/manual/migrations/existing-database.html.

This is what I get when I run hasura migrate apply --endpoint http://localhost:8080: FATA[0002] apply failed: [constraint-violation] the table "frequency" cannot be used as an enum because the table must have at least one row ($.args[2].args.tables[4])

Additional information:

1. The table frequency doesn’t have zero rows, it actually has 10 rows, at least that’s what I see on the original Heroku db that I ran hasura migrate create from.
2. frequency isn’t the only enum table, nor was it the first one that was created. I had another enum called archive_types and this was created first and is alphabetically earlier than frequency. This enum table also has values, but the console error doesn’t seem to mention it. Why would Hasura complain that that is something wrong with frequency but not with archive_types?
3. The only thing I did past hasura migrate create "init" was just create a test table, as stated in the guide.

Also I checked the files generated by the hasura migrate create "init" command, and it only seems to contain data about the whole Graphql/postgres schema itself (both the yaml and sql file). It doesn’t even contain a single actual row, i.e. my test data. Is there a way to migrate the data themselves too? It seems like migration isn’t that useful if it can’t do this.

@joshuarobs This should work (while we fix this with something better):

1. hasura migrate create "init" --from-server
2. pg_dump <postgres-url> --column-inserts --data-only -t frequency -t archive_types >> 15xxxx_init.sql
3. hasura migrate apply --endpoint prod-endpoint.com

You can add multiple -t flags for all the enum tables. Hope this helps!

this really needs a fix. It’s troublesome if you create the migration after making the enum tables or when refreshing the migration from scratch.
