Redwood v0.22 is upgraded to Prisma v2.12.1:

• https://github.com/prisma/prisma/releases/tag/2.12.0
• Rename findOne to findUnique

Generators will need to be updated accordingly.

NOTE: Prisma now included a Code Mod command. We can instruct users to run the code mod in the future to fix issue in their project.

In Screenshot below, disregard the Jest test failure. Just using this to show Prisma warning and code.

The scaffold generator uses findOne() in the generated service, we gotta update that!

@96RadhikaJadhav Want to take this one? This one actually generates the code that the other issue is documenting. This one's more awesome anyway. 😉

Just a heads up, the scaffold generator also changes the top level exports of @prisma/client so input types are now under Prisma namespace.

From the Prisma release notes

Before

import { PrismaClient, User, UserCreateInput } from '@prisma/client'

async function createUser(input: UserCreateInput): Promise<User> {
  return prisma.user.create(input)
}

After

import { PrismaClient, User, Prisma } from '@prisma/client'

async function createUser(input: Prisma.UserCreateInput): Promise<User> {
  return prisma.user.create(input)
}
