Does not seem to work with T3 stack out of the box 🤔

[MichaelOren]

Hey Chris,

Thanks for your work!

I can't seem to get it to work with a blank T3 stack out of the box

Outputted Prisma Schema

// This is your Prisma schema file,

npm install works fine and outputs the zod schemas fine.

After running npm run build I get the following error:

I have no idea how to debug this error 😅 , any help would be appreciated 🙏

im also running t3 and i got this error when installing in an existing repo:
Steps:
npm install zod-prisma-types

add to prisma schema

generator zod {
  provider = "zod-prisma-types"
}

$ prisma db push
Debugger attached.
Environment variables loaded from .env
Prisma schema loaded from prisma/schema.prisma
Datasource "db": MySQL database "db" at "127.0.0.1:3306"

The database is already in sync with the Prisma schema.

Running generate... (Use --skip-generate to skip the generators)
Error: Generator at zod-prisma-types could not start:

/bin/sh: zod-prisma-types: command not found

@MichaelOren thanks for the report! There ist a known issue with the latest version of zod. See #98. which Version of zod ist currently installed in a blank t3 Stack? Maybe this ist the cause dir this Bug?

[chrishoermann]

@fotoflo This seems to bei some other bug. I'll look into it.

[MichaelOren]

Thanks for the quick response!

This is from the package.json

    "zod": "^3.21.4",
    "zod-prisma-types": "^2.5.1"

Confirmed rolling back to zod to 3.21.1 got it working 😄

Closing this issue as duplicate of 98

[aronmal]

Rolling back zod to 3.21.1 helped me too. Looking forward for the fix of #98, but so far I am very pleased by this package and it helps a lot.

I also just noticed the known issues reference in the Readme.md, but I missed it the first time and found this issue first.
