Description

Hi, I'm experiencing no type checking when using Prisma's create method. This is really baffling as the generated type seem alright:

  export type ordersCreateInput = {
    ...
    meta?: PrismaJson._OrderMeta | NullableJsonNullValueInput
    ...
  }

In the method call however, I can assign any value I want to the meta field with no error:

this.prisma.orders
      .create({
        data: {
          ...
          meta: 10,
          ...
      })

Doing it this way will raise an error though:

const test: Prisma.ordersCreateInput['meta'] = 10;

Do you know what could it be?

I'll need a minimal reproduction repo to test it out :/

Type-checking doesn't work with:

previewFeatures = ["strictUndefinedChecks"]

I don't think it's the only reason as removing that flag doesn't seem to fix that in my production app, but it's a good start and we can iterate further when you look into that.

I fixed the strictUndefinedChecks problem with the latest release, would you mind testing it out again?

It seems Prisma client extensions cause the issue. See updated reproduction: https://github.com/rivatove/prisma-json-types-generator-418/blob/master/prisma/seed.ts

Thanks for the reproduction steps, sadly I do not have time to fix this right now but i'd love to review a PR fixing this.

Understandable. I'm putting a $120 bounty for anyone that fixes this and has his PR merged and released. Valid until such functionality is not supported natively by Prisma.

2025-02-08 EDIT: I'm cancelling the bounty because I stopped using Prisma extensions.

I'll work on this, let's me see if I can find a clever solution for this!

I'm experiencing the same issue. When my Prisma client includes any extensions, all type checking of input data is gone. Any update on if/when this might be fixed?

[arthurfiorette]

lets see if copilot can fix this one too!

Fixed in v4.0.1
