Why can't I access profile in user? (ORM) (Postgres)

    model User {
      id      Int      @id @default(autoincrement())
      email   String   @unique
      profile Profile?
    }

    model Profile {
      id     Int  @id @default(autoincrement())
      userId Int  @unique
      user   User @relation(fields: [userId], references: [id])
    }
