Unable to test custom scalars about graphql-modules

[devatina11yb]

This is actually related to the dual package hazard loading CJS and ESM packages from graphql-js at the same time so this is not directly related to graphql-modules. I am closing this issue here.

Hi @devatina11yb I was wondering if you found a solution for this as I'm also running into the same error and can't find much information about the issue.

I'm not completely sure why, but adding an alias for graphql to my vitest config (and removing the vitest cache node_modules/.vitest) appears to resolve the error.

/// <reference types="vitest" />

import { defineConfig } from 'vitest/config'

// https://vitejs.dev/config/
export default defineConfig({
    resolve: {
        alias: {
            graphql: 'graphql/index.js',
        },
    },
})
