What happened?

Hi, i have been in a trouble with the thing mentioned in title. This plugin has conflicts with "vite-plugin-istanbul".

Not working code

export default defineConfig({
  plugins: [react(), svgr(), istanbul({ cypress: true, requireEnv: false })],
  server: {
    port: 8000,
    host: "0.0.0.0",
  },
});

Working code

export default defineConfig({
  plugins: [react(), svgr(), istanbul({ cypress: true, requireEnv: true})],
  server: {
    port: 8000,
    host: "0.0.0.0",
  },
});

I would like to know why is this happening, it seems to have no-relation. The option failing if false is requireEnv.

Thanks.

Reproducible test case

//App.tsx
import React from "react";

import { Unity, useUnityContext } from "react-unity-webgl";

function App() {
  const { unityProvider } = useUnityContext({
    loaderUrl: "xxx",
    dataUrl: "xxx",
    frameworkUrl: "xxx",
    codeUrl: "xxx",
  });

  return (
    <div className="App">
      <Unity unityProvider={unityProvider} />
    </div>
  );
}

export default App;

//vite.config.ts

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import istanbul from "vite-plugin-istanbul";

export default defineConfig({
  plugins: [react(), istanbul({ cypress: true, requireEnv: false })],
});
