\x00 character in filenames using list template

Hi, Working on ubuntu 20, node 18, I export list template reports using this configuration in my vite.config.js :

import { visualizer } from 'rollup-plugin-visualizer'
import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import Checker from 'vite-plugin-checker'
import { ViteMinifyPlugin } from 'vite-plugin-minify'
import eslint from 'vite-plugin-eslint'

// https://vitejs.dev/config/
export default defineConfig({
    plugins: [
        react(),
        Checker({ typescript: true }),
        eslint(),
        ViteMinifyPlugin(),
        visualizer({
            template: 'list',
            gzipSize: true,
            brotliSize: true,
            filename: 'reports/bundle-report.txt',
        }),
    ],
    server: {
        proxy: {
            '/api': {
                target: 'http://localhost:8080',
                changeOrigin: true,
            },
        },
        open: true,
        port: 3000,
    },
    build: {
        outDir: 'build', // build folder
        sourcemap: false, // to ensure sourcemap are not generated even if the default change in futur version
        minify: true, // to ensure JS is minified even in futur version
        rollupOptions: {
            output: {
                manualChunks: {
                    mui: [
                        '@mui/icons-material',
                        '@mui/lab',
                        '@mui/material',
                        '@mui/styles',
                        '@mui/x-data-grid-pro',
                        '@mui/x-date-pickers-pro',
                    ],
                },
            },
        },
    },
})

I discovered that my output file contains a \x00 char at the beginning of some (always the same) filenames. Opening the report with vi, there are '^@' at the beginning of some names. Opening it with a text editor, the file is not readable (full of ideograms).

assets/date.formatter-OXGDuiJC.js:
  /src/misc/formatters/date.formatter.ts:
    rendered: 523
    gzip: 170
    brotli: 149
assets/exceljs.min-2QroBWrX.js:
  /node_modules/exceljs/dist/exceljs.min.js:
    rendered: 942732
    gzip: 255626
    brotli: 201422
  ^@/node_modules/exceljs/dist/exceljs.min.js?commonjs-module:
    rendered: 34
    gzip: 54
    brotli: 38
  ^@commonjs-dynamic-modules:
    rendered: 252
    gzip: 194
    brotli: 138
....

I tried to understand where this char is added, but could not find. All I know is that when I print the bundle variable in index.ts line 200, it is already present. A simple solution would be to call replace('\0', '') on file const line 103 of render-template.ts, even if it does not fix the original problem.
