"Operation not permitted" when calling GitDir.fromExisting

[erf]

I try to run GitDir.fromExisting(path) and i get the following error:

flutter: ProcessException: /bin/sh: /opt/homebrew/bin/git: Operation not permitted
flutter:   Command: git rev-parse --git-dir

I'm running the command fine from the Terminal

git rev-parse --git-dir

It seem the macOS app is not permitted to run the process, is there an Entitlement or an other way to fix this that you know of? I have used bookmark to get read/write access to the folder.

It's a macOS app and I'm on macOS 12.6 (21G115)

flutter --version

It works if i set the DebugProfile.entitlements com.apple.security.app-sandbox to false

.. but as I'd like to support the app on App Store it need to be in sandbox mode, so i guess this git functionality won't work ..?
