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

Hello, I just installed a fresh

create-t3-app

create-t3-app

with

prisma

prisma

tailwind

tailwind

, and

trpc

trpc

.

If we navigate to the example

getAll

getAll

query in

server/api/routers/example.ts

server/api/routers/example.ts

, and modify it as such:

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

  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

values

is strange:

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

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

In the past it would have looked like:

const values: Example[]

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

prisma

packages. So I created a fresh

create-t3-app

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.
