Hi All. I am having trouble trying to convert my filebase functions from the default CommonJS to newer such as NodeNextor EsNext. Ive followed some unoffical guides online but i keep getting the below error:

Error: Dynamic require of "fs" is not supported

# 
require('esbuild')
  .build({
    // the entry point file described above
    entryPoints: ['src/index.ts'],
    // the build folder location described above
    outfile: 'dist/index.js',
    bundle: true,
    platform: 'node',
    target: 'node16', // Target a compatible Node.js version
    format: 'esm', // Use CommonJS as the output format

    //sourcemap: 'inline',
    external: ['../../node_modules/*'],
    logLevel: 'info',
    tsconfig: './tsconfig.json',
  })
  .catch(() => process.exit(1))

the fix was the external parameter pointing to where node modules was for firebase functions
