TS conflict between zod + prisma in CreateOne, updateOne, upsertOne

[Paul Patterson]

Bug description

Hi, firstly, fantastic project, and thank you for your contributions!

With a default setup from the readme in this repo, there is a type error for the createOnePost / updateOnePost / upsertOnePost mutations in Post.router.ts - seemingly a conflict between the Zod Schemas + Prisma input types that are expected.

Dump of error from TS for createOnePost:

Argument of type '{ data: (PostCreateInput | PostUncheckedCreateInput) & (PostCreateInput | PostUncheckedCreateInput | undefined); }' is not assignable to parameter of type '{ select?: PostSelect | null | undefined; include?: PostInclude | null | undefined; data: (Without<PostCreateInput, PostUncheckedCreateInput> & PostUncheckedCreateInput) | (Without<...> & PostCreateInput); }'.
  Types of property 'data' are incompatible.
    Type '(PostCreateInput | PostUncheckedCreateInput) & (PostCreateInput | PostUncheckedCreateInput | undefined)' is not assignable to type '(Without<PostCreateInput, PostUncheckedCreateInput> & PostUncheckedCreateInput) | (Without<...> & PostCreateInput)'.
      Type 'PostCreateInput & PostUncheckedCreateInput' is not assignable to type '(Without<PostCreateInput, PostUncheckedCreateInput> & PostUncheckedCreateInput) | (Without<...> & PostCreateInput)'.
        Type 'PostCreateInput & PostUncheckedCreateInput' is not assignable to type 'Without<PostUncheckedCreateInput, PostCreateInput> & PostCreateInput'.
          Type 'PostCreateInput & PostUncheckedCreateInput' is not assignable to type 'Without<PostUncheckedCreateInput, PostCreateInput>'.
            Types of property 'id' are incompatible.
              Type 'number | undefined' is not assignable to type 'undefined'.
                Type 'number' is not assignable to type 'undefined'.ts(2345)

This happens in my turbo-repo setup, but I made a clean project to sanity check and the same error occurs.

Let me know how I can help, if possible.

How to reproduce

1. Create new repo following https://www.prisma.io/docs/getting-started/quickstart (basic prisma install + TS init + prisma init.)
2. Follow TRPC quickstart https://trpc.io/docs/quickstart (installing client + server)
3. Follow this repos quickstart (adding package + prisma models for user + post in readme, install zod)
4. Prisma Generate
5. Note type errors for createOne, updateOne, upsertOne actions

Expected behavior

No type errors preventing TS builds
