prisma client:

import { PrismaClient } from '@prisma/client'

const prismaClientSingleton = () => {
  return new PrismaClient()
}

type PrismaClientSingleton = ReturnType<typeof prismaClientSingleton>

const globalForPrisma = globalThis as unknown as {
  prisma: PrismaClientSingleton | undefined
}

const prisma = globalForPrisma.prisma ?? prismaClientSingleton()

export default prisma

if (process.env.NODE_ENV !== 'production') globalForPrisma.prisma = prisma

in the auth route removing:

adapter: PrismaAdapter(prisma)

will work fine but i want to store the data in th db
