Error using 3.5.4

[ZLJasonG]

After an npm update I get the following error from eslint suggesting an error or unexpected breaking changing in zod-validation-error@3.5.4 (it works fine when pinned back to using 3.5.3)

ESLint: 9.37.0

@ZLJasonG thanks for reporting this issue. Can you please run npm list zod-validation-error in the root directory of your project (after installing the latest v.3.5.4 and let me know what it reads?

I assume this is an npm dedupe error and not an actual error with zod-validation-error because if you check the package.json file yourself you will see that there's not a single reference of a /v4 subpath (outside the files property which is not really used in this case).

[jmike]

In short, some other dependency in your code must be using a previous version of zod-validation-error, hence your getting this error.

[jmike]

Hm, and you are getting the same error with this? sus

[ZLJasonG]

Sadly yes, thanks

[jmike]

I don't get it. There's not a single reference of v4 as a subpath or export in the code. Where is this error coming from?

Can I please ask one more thing... which zod version are you using?

[ZLJasonG]

running the eslint command

Here is the npm ls zod

1. Is it possible that you are importing from zod-validation-error/v4 somewhere in your code?
2. Assuming this is not the case, would it be too much to ask for a dummy repo that replicates this behaviour? I cannot reproduce the error locally as much as I've tried. I pinned eslint and zod to the exact version as yours, but linting passes without errors.

It seems to be an issue caused by the react-hooks eslint plugin - coming across the same issue myself. The plugin, imports var v4$1 = require('zod-validation-error/v4'); at line 20 of their development version, and jiti (when using a .ts eslint config) or esm/resolve (when using .js) cannot resolve due to the missing field in package.json.

at [projectDir]/node_modules/eslint-plugin-react-hooks/cjs/eslint-plugin-react-hooks.development.js:20:16

I suspect that the react team are doing something different locally so that they don't see this error (using a different resolver that doesn't rely on package.json fields). Downgrading to eslint-plugin-react-hooks@7.0.0 fixed the error for me.

Edit: Raised a bug on the react side.

We have zod-validation-error v3 as a dependency. Upgrading eslint-plugin-react-hooks to 7.0.1 exposed this error.

We are not yet ready to upgrade to Zod v4.

I fixed this error with a pnpm override:

{
    "overrides": {
        "eslint-plugin-react-hooks>zod-validation-error": "4.0.2"
    }
}

However, this raised another ESLint error:

A config object has a "plugins" key defined as an array of strings. It looks something like this:

    {
        "plugins": ["react-hooks"]
    }

Flat config requires "plugins" to be an object, like this:

    {
        plugins: {
            react-hooks: pluginObject
        }
    }
