I'm trying to create unit tests in NestJS with Prisma and found some examples and with the documentation on Prisma. Now trying to get it all working I'm running into some issues. context.ts

import { PrismaClient } from '.prisma/client';
import { mockDeep } from 'jest-mock-extended';
import { DeepMockProxy } from 'jest-mock-extended/lib/cjs/Mock';

export type Context = {
  prisma: PrismaClient;
};

export type MockContext = {
  prisma: DeepMockProxy<PrismaClient>;
};

export const createMockContext = (): MockContext => {
  return {
    prisma: mockDeep<PrismaClient>(),
  };
};

I'm getting the following error:

Type '{ $on: CalledWithMock<void, [eventType: "beforeExit", callback: (event: () => Promise<void>) => void]>; $connect: CalledWithMock<Promise<void>, []>; ... 13 more ...; readonly subMenu: DeepMockProxy<...>; } & PrismaClient<...>' is not assignable to type 'DeepMockProxy<PrismaClient<PrismaClientOptions, never, RejectOnNotFound | RejectPerOperation | undefined>>'.

    15     prisma: mockDeep<PrismaClient>(),
           ~~~~~~

      context.ts:10:3
        10   prisma: DeepMockProxy<PrismaClient>;
             ~~~~~~
        The expected type comes from property 'prisma' which is declared here on type 'MockContext'

Does anyone know why? Or how I can fix this?
