Strange trpc types

Hello, I just installed a fresh trpc project with prisma and next. I have a prisma schema such as:

model Example {
    id        String   @id @default(cuid())
    createdAt DateTime @default(now())
    updatedAt DateTime @updatedAt
}

model Example {
    id        String   @id @default(cuid())
    createdAt DateTime @default(now())
    updatedAt DateTime @updatedAt
}

and a router procedure like:

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

export const exampleRouter = createTRPCRouter({
  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> & {})[]>

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 projects? Is this expected behavior? I noticed this in my personal project when I updated to the latest prisma packages. It may be related to 4.16.x versions of prisma. I was curious if others were having this issue?

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;
  }),

  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> & {})[]>

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 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.
