prisma mock looks like this:
Copy code
import prisma from "@db/prisma";
import type { PrismaClient } from "@prisma/client";
import type { DeepMockProxy } from "jest-mock-extended";
import { mockDeep, mockReset } from "jest-mock-extended";

jest.mock("@db/prisma", () => ({
  __esModule: true,
  default: mockDeep<PrismaClient>(),
}));

beforeEach(() => {
  mockReset(prismaMock);
});

export const prismaMock = prisma as unknown as DeepMockProxy<PrismaClient>;
and the error I get looks like this:
Copy code
