If I run vitest run --coverage when using default's v8 system, everything works, and I get a proper text table with the coverage. But if I use now Istanbul instead, I get an error:

I have so far:
vitest.config.js:
import { defineConfig } from 'vite';import { svelte } from '@sveltejs/vite-plugin-svelte';import { resolve, dirname } from 'node:path'import { fileURLToPath } from 'node:url'import { configDefaults } from 'vitest/config'export default defineConfig({ plugins: [svelte()], test: { globals: true, exclude:[ ...configDefaults.exclude, '.direnv','tests/playwright/**/*' ], coverage: { provider: 'istanbul', // or 'v8' reporter: ['text'] }, environment: 'jsdom', alias: [ { find: /\$lib/, replacement: resolve(fileURLToPath(dirname(import.meta.url)), '/src/lib'), } ] }});vite.config.ts
import { sveltekit } from '@sveltejs/kit/vite';import { defineConfig } from 'vite';import istanbul from 'vite-plugin-istanbul';export default defineConfig({ plugins: [ sveltekit(), istanbul({ include: 'src/*', exclude: ['node_modules', 'tests/'], extension: ['.js', '.ts', '.svelte'], // VITE_COVERAGE=true to enable the plugin requireEnv: true }), ]});
