excludeFields doesn't seem to work

[sunnyatmoveai]

Apologies if I'm missing something basic but I've pored over the docs and this seems like it should work. I have this code:

import { Customer } from "@/models/customer"
import type { Resolvers } from "../resolver-types"
import { PrismaSelect } from "@/prisma"

export const queries: Resolvers = {
  Query: {
    customers(p, a, c, i) {
      const select = new PrismaSelect(i, {
        excludeFields: {
          user: ["fullName"],
        },
      }).value
      return Customer.list(select)
    },
  },
  User: {
    fullName(p) {
      return `${p.firstName} ${p.lastName}`
    },
  },
}

fullName is a computed field, as you can see in the User resolver, but when I run a query, it tries to ask prisma for fullName, which of course fails. I've tried everything I can think of but excludeFields just doesn't seem to work.
