Hey @arthur so their import tool doesn’t really work the greatest. I found what I usually had to do was just export the data from the database with a native database tool. For MySQL or Postgres you can use TablePlus. You have to usually export the data from the dev service, and import into a local docker container of a DB. And then do a TablePlus export, and do a heroku data upload as if you were just coming from the database directly rather than funneling it through using their export. Everyone is having tons of issues with their import/export tool with the relations specifically. I had a bunch when I was switching from graphcool to prisma 1

Thanks a lot @tmoney 🙂 I'll look at that
