Prisma-Heroku Postinstall Reproduction

How to Reproduce

git clone https://github.com/williamluke4/prisma-heroku-repoduction.git
cd prisma-heroku-repoduction
rm -rf ./.git
git init
git add . 
git commit -m 'Initial commit'
heroku login
heroku apps:create prisma-repoduction
heroku git:remote --app prisma-repoduction
heroku addons:create heroku-postgresql:hobby-dev
heroku pg:credentials:url

Now add the Postgres Connection URL to a root .env with the name DATABASE_URL.

DATABASE_URL="postgresql://__USER__:__PASSWORD__@__HOST__:__PORT__/__DATABASE__"

npx prisma migrate save --experimental --name "init"
npx prisma migrate up --experimental
heroku config:set NPM_CONFIG_LOGLEVEL=verbose 
git push heroku main

If you look at the build log you will see that the postinstall hook for @prisma/client is run. This initializes a sudo package in node_modules/.prisma/client/xx.

I created a postinstall hook that shows that even though @prisma/client postinstall is called, .prisma/client is not initialized.
