Strange trpc types with latest create-t3-app example app

Hello, I just installed a fresh create-t3-app with prisma, tailwind, and trpc.

If we navigate to the example getAll query in server/api/routers/example.ts, and modify it as such:

  getAll: publicProcedure.query(async ({ ctx }) => {
    const values = await ctx.prisma.example.findMany();
    return values;
  }),


The issue is that the TS type if we hover the mouse over values is strange:

const values: Prisma.PrismaPromise<(GetResult<{
    id: string;
    createdAt: Date;
    updatedAt: Date;
}, unknown> & {})[]>


In the past it would have looked like:

const values: Example[]


Has anyone else noticed this behavior in their project? Is this expected behavior? I noticed this in my personal project when I updated to the latest prisma packages. So I created a fresh create-t3-app to see if it was happening there as well, and was able to verify it was. It seems to potentially be related to prisma 4.16.x versions.
