Build fails in Deployment due to missing postinstall script

[RocketDav1d]

Currently it does not work to deploy my NextJS webapp with flagpack.
During the Vercel build the error is thrown that the postinstall script for flagpack is not found

Steps to Reproduce

This is my package.json
{ "name": "app", "version": "0.2.0", "private": true, "scripts": { "dev": "next dev", "build": "next build", "start": "next start", "lint": "next lint", "storybook": "storybook dev -p 6006", "build-storybook": "storybook build", "postinstall": "react-flagpack" }, "dependencies": { … "react-flagpack": "^2.0.6", … }, }
I've also tried removing the postinstall command or like this "postinstall": "flags-postinstall", "postinstall": "npx react-flagpack"

Logs

The logs in the Vercel console complain about not found "flags-postinstall"
