Unhandled Runtime Error: Prisma DMMF not found

[kachar]

We've stumbled upon the following error when we've introduced "prisma-extension-soft-delete": "1.0.0", in our app.

I'm raising the issue in this repo since the error is located in the prisma-extension-nested-operations code.

We're using turborepo and the lib is loaded from a sub-package located at packages/db/schema.prisma However the main app is unable to load the dependencies.

    "next": "^14.1.0",
    "next-auth": "^4.24.6",

    provider        = "prisma-client-js"
    previewFeatures = ["postgresqlExtensions"]
    extensions      = [pgcrypto, citext, uuidOssp(map: "uuid-ossp")]

generator zod {
    provider                         = "zod-prisma-types"
    createInputTypes                 = false
    createOptionalDefaultValuesTypes = true

}

The prisma schema is generated, all migrations are applied.

I think the problem is the Turborepo setup is storing the cached generated Prisma code in an unexpected place. The Turborepo docs say:

Prisma behaves differently with different package managers. This can lead to unpredictable results, which might lead to broken deployments in some situations. Instead of documenting the intricacies of each approach, we recommend not caching the results of prisma generate.

[rpaterson]

Actually I think it's not just Turborepo. Prisma has an output option to change the location of the generated Prisma client, but relations.ts is always trying to load it from the default location.

Here's how a similar extension solves this same issue: https://github.com/47ng/prisma-field-encryption?tab=readme-ov-file#custom-prisma-client-location

[rpaterson]

I looked at the this object passed to the extension by Prisma, and also the result of Prisma.getExtensionContext(this), but neither of them expose the DMMF as far as I can tell - I think the fix needs to be the same I linked above with the prisma-field-encryption extension: optionally pass in the DMMF.

@olivierwilkinson would you accept a patch to add this?
