@default(now()) and @updatedAt attributes. Then ran prisma db push, then opened a deploy request on PlanetScale. PlanetScale said the deploy would be safe. Then tried to deploy and got an error that updatedAt is not nullable and has no default value. How can I fix this? Why did PlanetScale say the deploy would be safe if it didn't work? And what I some resources I can look at to learn more about this, because I'm sure I'll have more complex schema changes in the future.
