Also instead of doing whatever you are doing in that db.ts file, use this:
import { PrismaClient } from '@prisma/client'
const prismaClientSingleton = () => {
return new PrismaClient()
}
declare global {
var prisma: undefined | ReturnType<typeof prismaClientSingleton>
}
const prisma = globalThis.prisma ?? prismaClientSingleton()
export default prisma
if (process.env.NODE_ENV !== 'production') globalThis.prisma = prisma

Did you do prisma migrate? What does your prisma schema looks like?
@Clown I just updated the problem, check it out to see the codes inside the file of scheme.prisma 👀
Do a prisma migrate
Not just generate

import { PrismaClient } from '@prisma/client'
const prismaClientSingleton = () => {
return new PrismaClient()
}
declare global {

const prisma = globalThis.prisma ?? prismaClientSingleton()
export default prisma
