Prisma

Hey everyone need some help after not working with prisma few months and i try to make it again here my issue when `prisma deploy`
```
  User
    ✖ You are creating a required relation, but there are already nodes that would violate that constraint.
  Department
    ✖ You are creating a required relation, but there are already nodes that would violate that constraint.
```

here my datamodel
```
type Department {
  createBy: User! @relation(name: "DepartmentsByUser")
  company: Company! @relation(name: "CompanyDepartments")
}

type Company {
  id: ID! @unique
  createBy: User! @relation(name: "CompanyByUser")
  department: [Department!]! @relation(name: "CompanyDepartments", onDelete: CASCADE)
}

type User {
  id: ID! @unique
  department: [Department!]! @relation(name: "DepartmentsByUser", onDelete: CASCADE)
  company: Company! @relation(name: "CompanyByUser", onDelete: CASCADE)
}
```

if you don't mind losing the old data, do `prisma delete` and then try again

You can't add an required relation/scalar field to existing nodes.

Thanks a lot <@U8L2D9TMJ> and <@UBRHXEVV0> `prisma delete` solve my problem and yes old data is not important i trying to back to use prisma again for my side projects
