Solution

The problem is related with the Vite resolver. Two workarounds are:

• Add resolver.alias property to vitest.config.ts:

resolve: {
    alias: [
      {
        find: "<YOUR_CLIENT_PATH>",
        replacement: resolve(__dirname, "<YOUR_CLIENT_PATH>/index.js"),
      },
    ],
  },

• Remove browser from the autogenerated Prisma client package.json.
