Describe the bug a type error in generated InputJsonValueSchema

Same here.

My temporary work around is transforming

export const InputJsonValueSchema: z.ZodType<Prisma.InputJsonValue> = z.lazy(() =>
  z.union([
    z.string(),
    z.number(),
    z.boolean(),
    z.object({ toJSON: z.function(z.tuple([]), z.any()) }),
    z.record(z.lazy(() => z.union([InputJsonValueSchema, z.literal(null)]))),
    z.array(z.lazy(() => z.union([InputJsonValueSchema, z.literal(null)]))),
  ])
);

into

export const InputJsonValueSchema: z.ZodType<Prisma.InputJsonValue> = z.lazy(() =>
  z.union([
    z.string(),
    z.number(),
    z.boolean(),
    z.record(z.lazy(() => InputJsonValueSchema)),
    z.array(z.lazy(() => InputJsonValueSchema)),
  ])
);

It would be nice to have a fix though 🙏🏻. @chrishoermann I just discovered this library and am really loving having it—thanks for your work!

You must use the strict mode or enable strictNullChecks in your tsconfig.json. It's worked to me.
