Hi Joe,
Unfortunatly I'm still stuck : Schema migration failed - Queries and Resources - Retool Forum
I would love to have an answer on my post. A week I'm in a team's plan and I can't leverage my staging environment. My app has to go in prod but can't plan for it until I have a dev env.
Right now I dev in prod because of this issue, not acceptable 
Edit : solved thanks to JoeBumbaca
